No it doesn't. What I do for this kind of series is the following. Put
an explicit CC (acked, reviews etc...) to each patch. git format-patch
$RANGE and then
$ git send-email --cc-cmd=./cc-cmd-only-cover.sh $DEFAULT_TO_CC --compose *.patch
$ cat cc-cmd-only-cover.sh
#!/bin/bash
if [[ $1 == *gitsendemail.msg* || $1 == *cover-letter* ]]; then
grep '<.*@.*>' -h *.patch | sed 's/^.*: //' | sort | uniq
fi
A bit error prone because you have to cleanup any previous patch files
from the directory but works more or less well for me.

we have an event notification mechanism. In v1 it is vmpressure and v2
you will get a notification when the high/max limit is hit or when we
hit the oom.
