Not really, it rather forces those who are serious about

why that? u publish the http record ONLY if u cannot publish the DNS one
And _everyone_ who is serious about having working SPF-enabled
mailservers has to look for it. In the current case, where _most_
domains do not have SPF records that means making http requests (that
will fail) for 90%+ of your inbound e-mail. Not going to happen.
Even _if_ you can figure out which servers to query.
Side note on the publishing side: are you going to run (and maintain) a
webserver on _every_ SPF protected host in your domain?
Even better. Then http records will be only used for a transitional
period until
and will vanish with the same speed DNS records become more available.
That would speed up the acceptance and implementation of SPF records..
Nice try, but there is no such thing as a _temporary_ hack when defining
a protocol, and the worst, ugliest hacks are the ones with the greatest
staying power.
