It's not clear to me what this resolution is about; could you please
elaborate (or give pointers)?
Is this about AEAD ciphers built on top of block-encrypt then mac? To some
extent, current GCM and CCM ciphers are already expanding the cipher text
length by the tag length, so I must be missing the point here. Thanks.

Best,
Alfredo
