The only thing I do to my new systems is installing oh-my-zsh, because that gives me a lot of goodies for basically zero configuration (I just use and learned the default presets to be "my own")
Last week I took a repo full of notes about the sizes of building materials and made inkscape and gimp "dependencies" of that project.
Next time I install Linux I think I'm going to make the filesystem immutable so that I not only don't configure it, but can't.
Now I've replaced it with a Hammerspoon script with some additions like setting my window layout based on where I am.
It's so much easier when you don't need to customise everything to the nines.
(I SO MUCH want to like and use Nix, but every time I've tried I've failed :D)
And same goes for the icons. I've personally never gotten there. but also, I don't look at the icons. They could be hidden. I know if I need to get to slack or email, it's on workspace one. So if the workspace badge says "1" or "1: Comms" or "" ... it doesn't really matter, because the keybind is muscle memory anyway. But on the flip side, because all of that is muscle memory... I might go "Where was my email at again? Workspace 1, or 2?" and having an envelope as the label makes it easier to find.
Different people have different workflows. And yes, some people are doing those things to sacrifice usability in the name of aesthetics, but some people may be GAINING usability by doing these things. People are vast and diverse.
I set this up many years ago and never changed it.

That's the only eye candy I would wish for in Sway or SwayFx.
I was a ricer before in my heydays of Linux, but now, after 25 years, I just use whatever comes by default with Xubuntu (XFCE) and a Macbook
My NixOS config was a much larger investment - that took a few weeks to debug. But I've used it for more than 4 years now, and it's been more stable than any other OS I've used. If you're not building it for satisfaction or /r/unixporn then you can afford to accommodate your creature comforts.
