So I really think that signing the top commit itself is fundamentally wrong.

That commit may not even be *yours*. You may have pulled it from a
sub-lieutenant as a fast-forward, or similar. Amending it later would
be actively very very *wrong*.

So quite frankly, I think the stuff in pu (or next?) is completely
mis-designed. Doing it in the commit is wrong for fundamental reasons,
which all boil down to a simple issue:

- you absolutely *need* to add the signature later. You *cannot* do
it at "git commit" time.

That's a fundamental issue both from a "workflow model" issue (ie you
want to sign stuff after it has passed testing etc, but you may need
to commit it in order to *get* testing), as well as from a
"fundamental git datastructures" issue (ie you would want to sign
commits that aren't yours.

"git commit --amend" is not the answer - that destroys the fundamental
concept of history being immutable, and while it works for your local
commits, it doesn't work for anybody elses commits, or for stuff you
already pushed out.

And "add a fake empty commit just for the signature" is not the answer
either - because that is clearly inferior to the tags we already had.

I dunno. Did I miss something? As far as I can tell, the signed tags
that we've had since day one are *clearly* much better in very
fundamental ways.
