Your argument applies to all kitchen sinks, regardless of whether they are considered one application like VSCode or an operating system withs collection of applications like Unix. Both still have all the capabilities for text editing, syntax highlighting, version control and executing scripts. You can spread complexity around in different ways but you can’t eliminate it.

Personally I find GUI discoverability to be like the hunt-and-peck model of typing, vs touch typing being CLI, and I don’t think it’s a coincidence that touch typing and CLI go hand in hand: you never leave home row. You think about what you want to do and type the command, instead of looking through panels of icons or more exotically arranged buttons (which in the newest web apps, constantly jump around as the page lazily loads, new elements appear forcing layout changes, fonts load causing text reflow… I frequently tap the wrong menu item because what I really wanted got pushed down by a new appearing element as my finger approached the screen.)

Maybe with something like PowerShell, with very consistent command names and arguments, this model is believable, but I don't know what other than memorization is going to tell you that "less" is for reading a file and "dd" is for copying one disk to another.
