Does github allow repository owners to send email directly to people who 
have submitted PRs or at least, people with commit privileges (in this 
case, those whose have done particular merges)?

Several of these were closed without merging and should not and cannot 
be backported.  For instance, you closed
https://github.com/python/cpython/pull/4225
after you submitted and merged a replacement.
https://github.com/python/cpython/pull/6259

Stripping backport labels off of rejected PRs could be considered.  But 
this would toss information needed for a new PR if the bpo issue is 
open.  Expecting either the submitter or merged of a replacement to go 
back and clean up the original seems a bit much.  The submitter might 
not be able to, and the merger might not know or forget that the PR is a 
replacement.  Perhaps rejected PRs should just be ignored.

Replacing 'closed' with 'merged' excludes rejected PRs.

The 2.7 backport of https://github.com/python/cpython/pull/3639
is yours.
