The bad thing that would happen is that it won't be up-to-date.

If you don't know what an outdated ref causes, then you don't know
what transport-helper does with it, and if you don't know that, why
are you bothering trying to review this patch? Is the purpose of a
patch to educate people?

Here it goes. The remote helper ref is going to be used to tell
fast-export which refs to negate (e.g. ^refs/testgit/origin/master),
so that extra commits are not generated, which the remote helper
should ignore anyway, because it should already have marks for those.
So doing two consecutive pushes, would push the commits twice.

It's worth noting this is the first time anybody asks what is the
negative effect of this not getting fixed.
