  expansion isn't the same as authentication tag

The size of the authentication tag contributes to the expansion by the AEAD, and it's probably the case that this will remain so, but the expansion could technically be larger (a CBC-mode AEAD for instance might have padding, see https://tools.ietf.org/html/draft-mcgrew-aead-aes-cbc-hmac-sha2-05#section-2.3).
