However, one notable difference is that RMX and similar ideas make use

This is a qualitative difference from having to set up some additional
server, though the exact flavor and degree of that difference isn't
clear (to me at least).
First thoughts:
DNS is cacheable, DNS is distributed, DNS has well developed authority
delegation structures, DNS behaviour as both a service and a control
point is well understood and exercised, requirements and costs for
running DNS (in whatever configuration) are well defined, and DNS
involves no inventions of new wheels with new threat models.
