I don't think so. You can have the signing key in the keyring, even if
that one was imported with only its own self-sigs.
Ultimately, I think the signatures should only be imported when they are
cross-signed by the key owner.
This would require a migration step were people signed the signatures
they already have on their key, but would otherwise allow them to keep
their 'precious signatures' they already have.
Then there should probably be a new command that would have to be used
to import the new signatures to your key that you are sent.
It won't fix the problem of a malicious keys being made with thousands
of fake signatures, but it pretty much solves the spamming problem by
only putting the owner in charge of accepting the signatures that can go
on his key.
