Yeah, I am beginning to think that is a sensible route. And it commits
us to nothing, so if we decide much later that a change of default is
sensible, that is still open to us.

I'm not sure how much you can achieve the "make it not matter". The
shorthands go a long way, but I still want git to read my mind about
which I wanted to use (and the closest approximation of that, from my
experience, would be a per-repo variable). However, having the
shorthands mean that we can try them out in the real world and revisit
the topic in a year if people still care.

I am not sure of that. I thought there was interest in full-tree grep
(OK, _I_ had some interst in it).  But the same transition pain
arguments apply there, and we should be able to do "git grep pattern :/"
soon, right?
