I have kept working on purple-mm-sms. Group MMS is now supported for recieving (any type of attachment) and is now suppoted for sending (but only text)!
The group MMS will not show up in chatty due to this: https://source.puri.sm/Librem5/chatty/-/issues/444 but they show up in pidgin.
For the most part, adding initial MMS support in purple-mm-sms is pretty complete (but needs testing and some bug fixes). The majority of the work is now integrating both a) into chatty and b) mmsd more completely into modemmanager.
Here is also a picture of me sending a Group MMS, via pidgin, from my Pinephone!
