You seem to prefer opinionated, where other people like the fact they can pick and choose from various plugins to my their IDE their own, and if they do not like the default implementation of a feature there likely is another plugin that may work for them.
For example there are a couple of git plugins, all of them act slighty different based on the workflow of the users of that plugin, if MS came in and said "No this is how git workflow is in VSCode and no other way is possible" that would turn off alot of users
Further you stated another glaring problem, Jetbrians mikes IDE's plural, specialized for each lang they are targeting, VSCode needs to work with many lang, there is not a VSCode:Python edition, and VSCode:Powershell edition, etc et c etc
It is just VSCode and plugins add the Languages you need / want support for
