I believe it would be useful to still have such a tool that one simply 
invokes as "mfh $COMMITID" for the quarterly branch as in the past.

https://docs.freebsd.org/en/articles/committers-guide/#ports-qa-misc-commit-mfh 
has instructions on how to do this manually, alas that is quite not 
as convenient - and hence likely to be used - as the nice original 
mfh tool.
