> Contrast this with Emacs and Vim. They just don’t have proper completion as an editor’s extension point. Rather, they expose low-level cursor and screen manipulation API, and then people implement competing completion frameworks on top of that!

This is just wrong, https://vimhelp.org/insert.txt.html#compl-omni

The first occurrence of "omni" I can find in the git log is this commit from 2012:

https://github.com/vim/vim/commit/5d3a8038b6a59e6f1b219f27ec...

which means it's even older
