I think that in general, we'd stop adding capabilities to v1. If you
have a client which speaks the new capability, then it should also be
speaking the new protocol. That's not strictly true if other non-git.git
implementations want to learn capability X but not protocol v2, but I
think in practice it's not an unreasonable world view.
I guess there may be a grey area for a while, though, where even
v2-capable clients don't end up speaking it, because they don't yet know
that a particular server can handle it. So any capabilities added in
that grey area may want to go to both v1 and v2.
