Yes we tried this fine granularity and stated that it was not working well. We are now using the bigger granularity that you describe below. > We should be sharding that at a much higher > granularity and using it much more consistently.

Yes I think it is now a good idea to split the mailing list traffic, at least for netdev and cryptodev. > Thomas in turn should by and large, > only be integrating pull requests.

Yes in an ideal organization, the last committer does only a last check that technical plan and fairness are respected. So it gives more time to coordinate the plans :) > B) Designate alternates to serve as backups for the maintainer when they > are unavailable.

About the merge window, I do not have a strong opinion about how it can be improved. However, I know that closing the window too early makes developer unhappy because it makes wait - between development start and its release - longer.
