I think that all breaking changes that are approved on this mailing list should be migrated to a much more visible Github issue (i.e. https://github.com/ghc/ghc) before final approval. You can still do all actual pull requests and coding via Phabricator, but the discussion should be on Github, because the barrier for new people to join in on the discussion is lower. You will get a lot more discussion and visibility into these changes purely by using Github as the central forum.

This mailing list is not an appropriate forum for discussion for several reasons:

A) The volume of email is too high. Only people who are experts at managing their inbox subscribe here.
B) There is too little signal to noise (for a beginner). Why would a beginner want to join a mailing list that debates such dry topics as whether or not to add Data.Intersperse.sequence?
C) There's no (easy) way to subscribe to (or mute) a particular thread (unlike Github where you can easily watch or mute specific issues)

Pretty much everybody on this mailing list is a die-hard Haskell expert and that's not representative of the Haskell community at large. Migrating important topics to Github will give us a more representative sampling of the community and will also help centralize the discussion better.

A point about process: I've been aware of this change for quite some time but I wasn't aware of the details (e.g. the changes to Data.List). It's easier to judge proposals like this if the complete list of changes are listed in some proposal page.
