Re: Entering, then cancelling, quiet mode causes builds to hang

Freezing the build—that is, the Groovy part—is deliberate, to prevent far worse problems, since we do not know when the actual JVM exit is going to come (TBD if we can safely block TermMilestone.COMPLETED). But the possibility that this mode would subsequently be cancelled was never considered. Pause + Resume is the appropriate workaround.

The whole idea of "Prepare for shutdown" is to allow us to finish the currently running jobs

It is to allow you to finish currently running freestyle (Maven, matrix, …) builds. So if you /safeRestart Jenkins will restart as soon as any of those are completed, and running Pipeline builds will be left alone.

Re: Entering, then cancelling, quiet mode causes builds to hang

ad #2 pipeline stops/freezes instead of expected and documented (e.g. also in UI "Manage Jenkins > Prepare for Shutdown") finishing of job:

this is surprising and unexpected considering also the documentation, but of course makes sense as described by Jesse.
however, would it make sense to change that to e.g. finish execution of currently active stage like commented in JENKINS-49365 – and somehow signal that in the UI similar to current "(part)" suffix in "build executor status" to allow for gentle shutdown at well-defined points? And therefore, as mentioned in JENKINS-49365, also when docker.image(...).inside(...) is used...

ad #3 pipeline does not wake up after canceling the shutdown mode:

yes, I can confirm: "pause" (also) after cancelling followed by "resume" works and would be an IMHO acceptable workaround – although I really would not mind if that would be "just" fixed, naively assuming that it is not that difficult to do?

While (resumable, i.e. non-docker.image(...).inside(...)-dependent) pipelines resume fine after a restart, there is a remainder in "build executor status" that (after the pipeline has finished) requires the workaround to abort it (the finished pipeline) by pressing the 'x' that in turn then asks "Are you sure you want to abort null?":
