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.
