It's true that there will be interim problems with corporate firewalls
(etc.) closing off outbound access to 587/tcp (but allowing access to
25/tcp). Should diminish over time. I suppose that's why alternatives
like POP-before-SMTP persist.

Not really, only relays.
On relay sites, implementation requires installing /usr/bin/srs (the
Perl Mail::SRS module) or equivalent, then using it as a wrapper for
.forward and /etc/alias entries. Over the longer term, it may end up
being supported inline in MTAs. Ditto for SPF itself.
