Yes, I agree. I'll try to implement the option and what you propose,
because it will give a better organization. So, the operation of
reloading could be summarized as:

keyring = (added keys + deprecated keys) - (removed keys - kept keys)

Yes, it is kind of intentional :) it needs some explanation.

The added keys must be a file with the complete public key that is
being imported, of course. But the removed keys don't need to. In the
current implementation, it is only a list of key identifiers and the
added keys are a real keyring, not just an export of a set of keys.

This seems contrived at first, as I thought when I saw it in apt-get,
but later I saw the purpose of it. We can manipulate the added keys
and select which ones will be imported. The above "equation" is an
example of such manipulation.

We can also change the extensions. I don't have a problem with that.
But this explanation may help the decision.

A: Because it obfuscates the reading.
Q: Why is top posting so bad?
