This is true, but so many distros ship bash-completion to the extent
that it can be assumed to be what we're dealing with for the purposes
of completion as third party software authors, so it can be considered
one and the same in this context.

I see. This is somewhat disappointing. To add some more context, what
I am actually trying to do at the moment is to make zsh completion
work for developers at work who are using CLI environments provisioned
via direnv and nix.

Currently direnv doesn't allow running things in the actual shell that
someone's using to e.g. set up completion:
https://github.com/direnv/direnv/issues/443
This *would* be okay in principle if I could just set an environment
variable to add more completions to zsh without nuking FPATH, but I
just found out that if direnv sets FPATH, it overwrites it rather than
appending/prepending it, which then breaks the default zsh functions
if the user's zshrc doesn't export FPATH.

This would, for instance, be resolved by searching XDG_DATA_DIRS for
completions, since it would not *directly* overwrite FPATH.
