What should happen if the version discovered here is different from
v2 or the capabilities offered are different from what we saw
before? Perhaps we need some sanity checks, as we on this side of
the connection know we are making two requests, and may even end up
talking with an instance of "upload-archive" that is different from
the one we talked with earlier.

This is somewhat curious. The upload-pack going over HTTP also is
triggered by the same "stateless-connect" remote helper command, as
we just saw in the previous hunk, and that support is not new. Why
do we need this change then? What's different between the "data"
that is obtained by get_helper(transport) for driving upload-pack
and upload-archive? Presumably upload-pack was working without this
change because it also sets the connect bit on, and upload-archive
does not work without this change because it does not? Why do these
two behave differently?
