I guess I could probably just push the final merge commit as a tree, but
it would require me to very strongly resist my compulsive urge not to
push something that doesn't even build.

I suppose if we could write that down into some kind of rule I could go
look at it until the compulsiveness wears down... =)

almost ready to push out.
