where do you want to place it?
in subkey binding sig?
that would be odd..
because this means creating another binding sig (when making new subkey(s)),
and OpenPGP does not allow multiple binding sigs (unlike userid self sig),
and then keyserver problems, etc..

I think it may be better to put this in userid self sig
(this would allow different subkeys for different userids),
but then format can't be like "primary user id" ( subpacket,
it can be like Issuer ( or even better
like Revocation key ( subpacket
