I really don't see all of OpenDev moving to Matrix - I saw Zuul was considering it, which is unfortunate[1] :/ - now the various projects are going to be fragmented.
1 - I trust there was good reasons, the Zuul folks are great, but it means potentially another chat client for me for channels I use infrequently at best
Moving to Matrix really shouldn't be disruptive, given how easy it is to then bright Matrix back into IRC on whatever network. (Admittedly the Freenode mess has made bridging problematic given the loss of identity/access data on the Freenode side means we don't know who has permission to re-plumb, but we're working on that)
Yeah - looking at the mailing list discussions, it seems people find bridged channels not as "nice"? [1], but in the long run, I think a move to matrix would stave off the "move to slack so I get a GUI / bouncer / etc" discussions that come up a lot.
For all/nearly all of the open infra projects the freenode mess won't be as bad, as we migrated en-mass to OFTC fairly quickly after it kicked off.
