Seems like that patch just got no replies at the time. FWIW I'd very
much be for it and would encourage you to re-submit it.

I'm not sure s/shared/contrib/g is the best naming though, but maybe I'm
contributing to needless bikeshedding by mentioning that.

You apparently named it like that to match where distros usually install
it (/usr/share), but we also have docs there, locale, and the perl/
directory usually (well, at least on my distro) ends up there.

I wonder if just a top-level completion/* wouldn't be best, or if we
want to group them all together something like
optional/{completion,credential}/ or other name suggesting that these
are meant to interact with not-always-present 3rd party software. Maybe
integrations/* ?

For some of these names a general re-arrangement of contrib/* would be a
logical thing to follow, e.g. I think it would make sense to carve out
various ci/, contrib/coccinelle, Documentation/doc-diff,
check-builtins.sh etc. and other "only for supporting git.git
development" or "only called by our own Makefile(s)" into some
consistently named pattern.

I'm also very much in favor of building and testing all of this software
by default, to the best of our ability. We've had some avoidable bitrot
e.g. in subtree and mw-to-git in the past, some of that is a pain to
test (e.g. requiring an installed MediaWiki), but we can usually
build/test some part of it (e.g. in that case, does it even compile as
Perl code?). In other cases we could compile/test things by default on
certain platforms if they're platform-specific.
