Interesting, yes.
Hopefully the momentum for dual funding will grow as that will be a big part of payjoin making more sense to people (obviously there are various flavours of ideas that overlap, even splicing as well, but my point is mainly that it's in the LN related niche that this will find its best home, straightforward payments were always a tough sell to merchants so user wallets never got that enthused).
(Side note, but curious as to why JM has a random reddit link instead of the 0.7 release notes or the Payjoin docs in the repo? https://github.com/JoinMarket-Org/joinmarket-clientserver/blob/master/docs/PAYJOIN.md
It was bad enough having to wait literally 2 years for Luke, or whoever it was, to merge the fact that JM supported payjoin in BIP78 references 😆 despite the fact that it was implemented straight away (also we had another version of payjoin originally that was custom, before bip78).)
