Yeah I agree. (I personally run a user shepherd, itself starting a user
mcron, but I admit that’s a config not everyone may be willing to
replicate.)

Agreed!
That brings us to my first proposal above: writing a crond service that
runs mcron’s crond. Would you like to give it a try?
(There’s also scron available. I think someone had proposed a service
for it, but I can’t find it.)
Thanks,
Ludo’.
