Unable to issue subkey revocation

[Chris DeYoung]

I don't claim to have anything approaching the technical expertise of 
several of the people who have already addressed the issue, but 
nonetheless I think I have followed the explanation reasonably well (and 
I invite correction if I'm mistaken).

That said,

> No. It does not revoke the subkey.

It doesn't need to. The subkey is automatically invalid because the 
primary key associated with it is invalid (revoked). Any system using 
the subkey *must* check this; failure to do so means potentially 
trusting an invalid key - no different than using the primary key 
without checking whether it has been revoked.

It seems like you want to require that the subkey itself is also 
explicitly revoked, but this is neither necessary nor required, so 
failure to do so is not a bug.

Am I wrong?
