Welcome back!

I have no strong opinions, in regards to the acks.

Your current approach, with no ack at all, just means that I have to
do "git remote update" a few times, which I probably would have done
anyways. So, to me, feel free to pick whatever option that makes the
life easiest for you.

Kind regards
