We have added the directory after someone specifically asked for a place
to install completion files to:
People may be using the directories with private packages, like the
submitter of the bug.
Introducing the directories makes sense, because it allows upstream, us
packagers and admins a maximum amount of control of function files:
1. If the file is in /usr/local/share/zsh/site-functions it is used
(this is the the-admin-always-wins option) no matter what.
2. If the file is in one of the debian-specific "vendor-*"
directories, any package different from zsh may add new or override
functions shipped with zsh (this is the
3. If the two previous options don't trigger, use zsh's functions from
the rest of its $fpath (this is the fall-back-to-zsh option).

There is nothing to warn about. The `vendor-functions' directory is only
of concern for debian packages. And the maintainer of the package needs
to make sure it is used.
Starting with debian's 4.3.12-1 packages these directories are active.
And they will remain active, because it makes sense for us as a vendor
to provide directories like that, as I outlined above.

It shouldn't. For example, that wouldn't work if zsh was compiled with
the `--enable-function-subdirs' compile-time option to remedy the
Debian builds its packages like that and personally, I'm doing that as
In protocol design, perfection has been reached not when there is
nothing left to add, but when there is nothing left to take away.
