This produces a change in behavior dependent upon whether the user has requested a region-based ePSF, or a per-detector/per-region based ePSF. That might cause confusion down the line when interpreting this metadata value, requiring an if/else or a try/except, or somehow parsing the detectors_focal_plane_regions parameter further downstream.
My suggestion instead is to also construct a dict here with a single entry. The key can be something simple like "full" or "all" (or something else you feel appropriate), and the value can be this summed number. Then, downstream, we can simply iterate over all psfStarCountDict.items() or psfStarCountDict.values() to get the metadata we need. Does that sound like a good idea here?

Yes, I agree with you and it sounds like a good idea! I made modifications based on your comment.

Great, thanks Amir, this looks great!

As you did for validStarCount and allStarCount, I'd suggest also adding a small in-line comment here to describe what this psfStarCount code block is doing. (Both here, and replicated above for the non-regions approach).
