[ietf-dkim] another try at my question on options in TXT records

[Tony Hansen]

Since my question before was hijacked by a totally different thread, I'm
going to ask again under another thread:

We allow extra options to be specified in a DKIM-Signature header, but
do not allow extra options to be specified in a DKIM TXT record. (I
don't recall this being discussed before, but just may not remember it.)
Should we? If not, how would we do upwardly-compatible changes without
requiring multiple DNS entries for both an old and new entry?
