It is a bug, in my opinion. If we were not planning on changing the
default, I would say drop the warning altogether.
*But*, if we are going to change the default, the warning can be
repurposed to say "in the future this will fail". That requires other
changes though.

Exactly. And we can choose between those behaviors with a
configuration, like it happened with push.default.

Existing users that are using up-to-date distributions, maybe. Debian
stable is using v2.20.1. In general it's not a good idea to assume
anything about our users. Recently a user of Oh My Zsh reported an
issue with the backwards compatibility code of git-completion; he was
using v2.17 I think.
That is exemplified by the fact that this whole thread started from a
user that refused to configure pull.rebase and expected the Git
project to just do the right thing (which is basically choosing a
useful default).
Cheers.
