I think this is a problem that should be tackled in vendor packages.

Here's how we do it in debian land, using build-time parameters passed
to the ‘configure’ script: We set the ‘site-functions’ location to
/usr/local by using:


This solves the problem of site-specific additions out of the scope of
the package system. Now there's the problem, that other packages, that
may want to install zsh completions can't just write to /usr/local... To
solve that we use


And we just tell other packages to install completions to


This would solve what you're asking for, in addition to leaving a clean
place for completions from other packages in a vendor's repository.
