Hmm.

That branch seems to have sprouted another commit just today.

I ended up taking that too as trivial, but it shows how you seem to
basically send me a pointer to a live branch. Please don't do that.
When you make changes to that branch, I now get those changes that you
may not have meant to send me (and that I get upset for being
surprised by).

An easy solution to that is to send me a signed tag instead of a
pointer to a branch. Then you can continue to update the branch, while
the tag stays stable.

Plus we've been encouraging signed tags for pull requests anyway.
