clear up whether adding the prefix breaks wildcards, or were they already

Since I don't know what you mean by "broken", I can't comment to whether or
not wildcards are "already broken". BUT, if you publish:
*.example.com. IN TXT "v=spf1 ..."
*.example.com. IN TXT"spf2.0/pra ..."
Then, if a query for "host.example.com IN TXT" would match the wildcard, the a
query for "_marid.host.example.com IN TXT" would ALSO match the wildcard.
So, the problem isn't that wildcards and marid records don't work, it is just
that when using wildcards, the _marid prefix no longer gets you *just* the
spf2.0/pra record. I.e. the current status quo.
