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.
