In my understanding, these are different concepts. In particular, RMX doesn't hijack the TXT record, which is one of the major sins of SPF.
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.
