If by "gradual transition" you mean place the contrib/remote-helpers in
another directory before removing the code, I do think it's a waste of
time, but I don't really care, as long as eventually stubs are put in

You can add such change in the release notes. Other than that I don't
see what we could do.

How many people copy the scripts every time they update Git? Not many
I'd gather.

We could. Personally I don't see the point of making the warning any
more annoying. The instructiosn are just one click away, and if they
have no time for that, they can just ignore the warning.

To me the endgame is that the code is removed, and only stubs remain.
What you do after that is up to you.

I meant I want 3. eventually, hopefully for v2.1.

You did not specify those were only for v2.0.

No, I don't want them crippled for v2.0. A warning should suffice.
