You don't really believe that, do you? Competent users tend to have preferences. There's no need to worry about installing plugins if you have to have a .vimrc to begin with, just have the .vimrc do the installing as well.
Which means newcomer text editors need less configuration, and users generally staying closer to the default stable, tested configuration.
You can argue that you're part of a margin needing XYZ specific setting, or that new programs don't necessarily make good default config choices. To me it feels generally reasonable to believe so.
Case in point, with text editors / light IDEs. I did Sublime Text -> Atom -> VSCode. At each step, the size of my config size decreased. Of course I still have a VSCode settings.json, but it's twenty lines. My sublime prefs are ~100 lines, my .vimrc is hundreds :)
There are additional perks to including things by default, too. Jump mode is a good example of that: it's integrated with its select mode. You can start a selection and then switch to jump mode to move the cursor to complete the selection.
Lastly, there's simplicity in including things rather than asking new users to pick from a dizzying array of plug-in options. Rails is a good example of this: there's a lot of functionality that could have been left to 3rd-party gems, but having the framework include them by default means they'll work out of the box, and there's a single canonical solution to [sessions, templates, ORM, routing, etc].
I'm going to resist adding everything but the kitchen sink to Amp. Upcoming features like tasks and language server protocol support will allow Amp to integrate with language/framework-specific tools as easily as possible, but without steering Amp towards any specific choices. I couldn't avoid that with syntax highlighting; it's just too essential (and it powers the symbol jump mode). It's definitely a balancing act!
As for a file finder, I'm curious how you can use a separate tab to open that in the current instance of Vim? From when I'd last used it, most folks were using Ctrl-P to solve that problem, and usually with an external indexer like fzf or ag.
The best thing is to provide some sensible overridable defaults and basic functionality expected these days from a programmer's editor, such as simple project management: index files, fuzzy file finder, etc. Vim and Emacs are a pain in the butt for precisely this reason: they don't take ANY decision, they just throw the entire burden on the user. They're forgiven because they're classics, but any kind of editor launched in 2018 would be utterly ignored if it didn't have these features.
I don't think so. I've never felt that having 10 linux distributions was a problem, I just can pick between at least two super robust choices : Debain, RedHat. I can even choose between inkscape, krita, gimp. Or KDE and Gnome...
You can argue that progress would be faster if we have less choices but more choices also means more developpers...

This is BTW no limited to OSS but AFAIK it comes from sales-research. People confronted with to many products of similar type can end in a deadlock, avoiding those products or even start to avoid the whole category.

More developers reinventing the wheel doesn't automatically make the wheels faster. It can mean healthy competition, but it also can mean wasted ressources. It's case by case.
On the other hand it can hurt - for example I'd like to have my main workstation running mainly one gui framework. (Or at least, most of the software). But the KDE/GTK split makes the most popular and sensible software to use for most cases pretty much evenly distributed between those two. (Though this is obviously not a major issue, just an example).
And that's just for Vimscript plug-ins. There are several situations (e.g. fuzzy file finders) where external binaries are preferable, for performance reasons. The idea is to include those directly in Amp, so that it's _only_ a configuration file that's needed, if at all.
That said, Amp doesn't have plug-in support at the moment, so it's a little unfair for me to judge Vim on that front. But if it did, the package management portion would be baked in so that you'd only need to pull your configuration file and Amp would handle the rest. :)
Just install it and use it. Works.
I like projects that provide similar experience.
