I don't use ERC, but how does it make sense to change the default so
close to a release?  I could understand reverting back to 'buffer',
which was used for a long time, but switching to a new default that
had no real testing period?  Are you absolutely sure this is a good
idea?  And on top of that, change it only for Emacs 29?
