at that point… use vim? genuinely asking. what does this get you?
You can just… not update them.
These days you can probably install mini.vim to get basically every paper cut fixed (eg extra "surround objects", aligning text, plugin manager etc), a theme, a few other assortments to taste and park your plugins at known commits or include them in your dotfiles and its ... fine. I haven't updated my plugins in probably 6 months and when I do I update them selectively only if there is actually a reason to do it or the changes are very minor.
