This like lego just pickup few templet and build project. but forget lego build only toy car not real car

This not IDE. If better to use notepad++ instead to use this. First come out mentality of google. In search result, Android, YouTube and etc. In all of this user has few access its necessary because most of user don't know consequence of give him access so you take responsibly its ok but in dev you understand that not normal user.

For example, window OS when you delete file ask permission and send to recycle bin also you don't delete system file. In Linux just single cmd entire disk erase.
why they chose different approach because they know which they target
if give normal user access cmd like rm In window what happen you understand

I use google colab but what make no sense if not access to terminal in it
First of all you clear your vision you make serious Dev tool or just rewrite history with another failure

that IDE need to lot of improvement
For case study use replit.com that far better than your IDE
your IDE use vs code it make no sense to better it

If you serious about it than create IDE and public resp ask dev to improve this IDE
second not take charge for all thing. dev know what they do if you just provide resource for dev not provide workspace. they need they create they need template they create it
you provide recourse and environment there build what they want to build you don't tell them what they build what they dont build
