Had some free time, figured I'd try see if I could get the amenity automation bug in vanilla.
I think I got it? I got something.

Asgard Prime has been on these automation settings for a couple years - I manually built a robot plant, and automation made a city district for housing. Automation is working fine - other planets are updating their amenity jobs and building things as expected.
Except none of the maintenance drone jobs on this colony have been closed, despite it only needing one.
In this example, automation wakes up about 6 months after the save is resumed and starts closing the jobs as expected, though in other (modded) games I've seen amenity automation do nothing for much longer periods, including with pops working the excess amenity jobs.
Hopefully this is useful.
