The scenario you describe is very reasonable to me, indeed the user might feel lost looking for an option that is not there because it's only in the priority list.

I'm +1 on doing this change, but I think it might be better for it either to be in a separate commit and having its own changelog, or in an entirely new pull request, so that it's easier to track. It might be worth to make the first change for other helpers following the way time zone select works, then change everything as you propose.

Feedback from others regarding this is also very welcome.
