I was thinking all fixes will have "Cc: stable" tag, to be sure all
fixes sent to stable mail list, and you will be the picking for stable tree.

Now you are suggesting some fixes may have "Fixes:" tag but not "Cc:
stable" tag.

So this means now author/maintainer/committer will be the picking
patches for stable tree, and to show this decision, will add "Cc:
stable" to the commit log.

If author puts the "Cc: stable" tag, git send-email will ensure this
patch will be sent to stable mail list too.
But if author missed the "Cc: stable" tag, will it be enough for you if
committer adds the tag into commit log? Or should patch sent to stable
mail list too?

What is the relation between "Cc: stable" tag been in commit log and
patch been sent to stable mail list?
