I agree, that's why I sent patches that:

 1) Add a warning for v2.0 (which already has problems)

    So everything keeps working as well as in the release candidates,
    except a warning is introduced each time they do a fetch, push, or
    clone operation (use the remote-helpers)

 2) Replace the tools with stubs

    So when they try to fetch, push, or clone, they get an error, and
    nothing else happens.

There's an additional README for the people that want to read more, but
if you don't put stubs, users might try to do what worked before:

  % git clone hg::
  fatal: Unable to find remote helper for 'hg'

It's much better to report:

  git-remote-hg is now maintained independently.

That's right, you have the legal right to distributed it.

It is not my wish to disrupt v2.0, so I think adding a warning should be

Eventually I would prefer if they were not distributed, and replaced
with stubs, not just because it would help the out-of-tree projects
gather more visibility, but also because users would be better served by
not having poorly maintained or unsynchronized code. Hopefully for v2.1.

As far as I understand most distributions don't do anything special with
contrib, they just put everything under /usr/share.

It is unlikely packagers will notice any change in one of the dozens
tools in contrib, so they'll make no changes to the packages.

So if the user did:

 % ln -s /usr/share/git/remote-helpers/git-remote-hg ~/bin/git-remote-hg

The expectation would be that this keeps working even if the package
doesn't change (it just adds a warning). Eventually it will stop working
with an error, but the package still won't change.

The distributions that do something special about remote-helpers (AFAIK
it's only debian's git-bzr) would need to change, and sooner or later
they will if there's only stubs there.
