[INTPenis]

Seems like a lot of training wheels to me. I mean linting, formatting can be done by piping buffer into external programs. Not sure what back end integration means but you can accomplish a lot with just bash+vim+tmux (or zellij which I recently switched to).

The disadvantage is of course that it's not integrated, but the advantage is that my editor never crawls to a halt.

Training wheels isn't a fair characterization, the IDE tools are just better for a lot of use cases. I haven't had an IDE grind to a halt since earlier versions of IntelliJ on some large codebases back in ~2016 where the internal linting process lost the plot. Mostly they're just memory hungry and they start up slower.
