3) SPF uses a distinct "magic number" similar to the Unix file magic

cause problems and so that SPF records can be easily filtered out if
you don't want them. The pre-existing uses of TXT records do not
come close to colliding with SPF records.
The reasons why SPF is badly wrong in using TXT records are explained
in the Internet-draft "Design Choices When Expanding DNS" by
P. Faltstrom and R. Austein (draft-ymbk-dns-choices-00.txt) and you
did not reply to them.
