I'm not sure what rationale would satisfy you. In my mind, the idea of extending a face up to the margin of the window seems quite decoupled from whether that line has a newline at the end or not. It's purely visual. If I'm using a face that extends in all lines, for example, I find weird that it does or does not extend in the last one depending of a newline. (Again: I agree that's how it is defined now, I'm not questioning that.)

Yes. I happen to use bs-show, and hl-line-mode in bs-show, so it's not obscure for me, obviously. (Years ago I defined the format of my bs lines to fill entirely the window with spaces to avoid this ugly "ragged" effect on the last one.) But whether it will be useful in other cases will depend on how frequent is to have buffers with a non-newline last line, I suppose. No idea.

Yes. It was quite "entertaining", so to speak.
