I know, but removing it where you remove it has mostly no effect (it's
normally run from a major-mode body, so all the vars have been set
back to their global value).

That's fine.  But doing it where you currently do it is a waste.

Doesn't show-paren-mode do that?

BTW, feel free to commit your current code in the mean time.
