I think you have the right idea. upsc/upsd see the ups.status value, but while setting things up, it is useful for the driver debug messages to explicitly say what is detected (and what will be written to ups.status).

Probably not now. I might ask again after adding a few more debug messages.

Disappointing. I will add a note in the man page for that, too. (Maybe it is only after the UPS is in the low battery state? You mentioned that it did shut down when you did the capture with the Windows software.)
