I stick with regular vi for a very long time because of this. I was a systems consultant way back when and I'd have to work on several variants of unix that had a mich-too-long lag time on getting vim ports. Iirc, sparc was the unix that took the longest in getting a gnu tools pipeline, so once they had vim and I could reasonably expect most of my customers could install it, I switched.

I now do a pretty standard config (mostly use the vim plugin in VSCode since I'm a software dev nowadays).
