I think you may have misunderstood?

My main editor is IDEA, followed by vscode and emacs. But all three are set to vim mode. Vim itself has actually never been my primary editor; I generally only use it when I'm sshed into servers.

The thing that vim mode gets me is twofold: It (mostly) unifies the editing interface among all of those editors, and it allows me to edit code more quickly.

The thing I was talking about above is not indenting - my autoformatter does that for me. The thing I was talking about is (a sort of hacky version of) syntactically aware editing that allows me to quickly do large-scale operations without having to explicitly fiddle with the cursor.
