just my 2c: for me the current situation is fine:

i can thumb through the commit emails.
i can sort by sender and dispose of them.
or create a message filter to do that.

and its good to have them searchable should
i need ever to do that.

i am used to receive lots of email and
thumb through them; whether its one email
or 50 a day is not a problem for me.
thanks,
wolfgang
