But there are plenty of projects that will only accept patches
formatted and sent by "git send-email".  If you send them an attachment
with a patch, they might complain and ask you to send it back again
using "git send-email".

Once again, I don't think we disagree on anything substantial here.  You
have already said that it is fine to implement support for both, and
everything beyond that should not matter for the proposal.
