That's no more than reading base 64 in, convertingh it to binary and following
the packet formats. The internal format is well documented in RFC 4880.
That is a far cry from the keyservers being able to do verifications

At present, they don't. The owner would need to sign the submission to certify
he is doing the submission, hence the need for crypto.

That step would also need crypto as the keyserver would need to verify the
signature on the packet containing the flag.
