I do not know why you or anybody can think it is safe from what you
observed above, though.  Who or which page of what manual told us
that the key owner's identity part cannot be missing?

Yes, as a code clean-up topic, I think it is the *only* acceptable
thing to do.  Finding the source to justify tightening of the rule
to validate data to insist we have to see 3 pieces can be left to a
separate topic once this series settles.
