I can't tell the future at the moment; I updated the OS on my crystal ball a few months ago and it still hasn't rebooted yet.
It's quite possible that at some point, somebody might want more 2G systems, Ericsson or not. Run by Telecomunicaciones Indígenas Comunitarias, or not, - and/or 2G/LTE or even whateverG else is around then.
Improved MGW support for E1 is of course, er.. an improvement. Lack of AMR there would be on my list of laments for what I was unable to get done (yet), along with all those other things to do with audio quality with AMR + DTX and all those weird things to do with RTP streams and audio on the radio interface, that Mychaela seems to be quite passionate about.
Also listed would be, multiple radio support in osmo-bsc on the DUG, and quite a big lament; - Lack of dual mode radio support for a 2G/4G combination on one RUS/sector. Anyway, no, I don't have any use case for it at the moment, and my motivations for spending hours coding 2G had diminished somewhat along with TIC-AC's changes in direction, and the pandemic... and the war.. and the genocide.... Besides, after all these years, well.. the femto BTS (osmo-bts) based systems are working now very stable, although rough working conditions has taken its toll on a lot of that radio equipment.
And, it seems the the flood of Ericsson equipment onto the second hand market that was once anticipated has yet to materialise.
Anyway, all I really wanted to say was that I don't see any evidence that osmocom community considers anything "rogue" and if that was interpreted from a comment* of mine, it should not have been.
* now as I write realising that comment was offlist.
