Your middle example above did make me think of one other thing, though.
As you noted, we actually have _three_ signature types:

  1. signed tags

  2. signed commits

  3. merges with embedded mergetag headers

We already have a tool for (1). Michael is adding a tool for (2). How
would one check (3) in a similar way?

Hmph, somehow I misread the patch that it was for both 2 & 3 X-<.

I was just assuming it handles only (2) without checking further, so I
may be wrong. But I do not think it makes sense to conflate (2) and (3).
A merge commit may have both, and they are separate signatures.

For that matter, is there a way to expose (3) currently, besides via
--show-signature? It does not trigger "%GG" and friends (nor should it).
It may make sense to add extra format specifiers for mergetag
signatures. Though I do not use them myself, so I am not clear on what
the use case is besides a manual, human verification of a particular
merge.
