In my understanding, these are different concepts. In particular, RMX

Yes, but they both were designed to do the same work. SPF however can do
more. TXT was used because nothing else could, at least I think so.
They could have used a prefix "host" to avoid hijacking the main
TXT record. (So you'd query the TXT record for
"__spf__.domain.tld" or something like that instead of the TXT
record for "domain.tld" when checking SPF.
Could of, but underscores are not a legal character in domain names.
no, they are perfectly legal "in domain names". They are being used in
DKIM. don't confuse with hostnames.
And now BIND 9.4 supports the SPF RR type, so we just have to wait a
decade or two until everyone still running bind 4.0 has a chance to
upgrade.... ;-)
and a century until everyone has a chance to upgrade their mail software
to use the new record ;-p
