I think a fairly large number of people using IDEs use them for the writing code coding part almost exclusively, e.g. don't use many/any of the other "integrated" features like VCS integration, build integration, etc. As an example, I think most people I've seen use vscode still use git via the cli (less sure but I'd guess most of them use a separate terminal even).

I don't know for sure or have anything besides anecdotal evidence but I'd wager this is a majority of vscode users.
