on my system 3 out of 14 are doing this.

And e.g. mlocate updating its database also on a desktop/laptop that is 
not runnning during the night is not useless and not having this would
be a real downside.

The praxis to favor is to check the impact instead of blindly removing
functionality.

"happen more and more" means it might never happen 100%,
for that you would need policy making it mandatory first.

Short-term for buster, installing anacron still looks appropriate.

And compared to everything else that is running on our default desktop, 
anacron does not create any noticable overhead.

Calling anacron a separate system is not correct, it works on the normal 
cron jobs (ideally this functionality should have been implemented in 
cron itself).
