May be because for codecs internal work SAR feels more important? If PAR
(in the sense of ratio between coded picture width and height) can be
derived in exact way from SAR and DAR - then I see why ffmpeg opted to not
carry it .. But confusing, yes.

I guess from ffprobe reports it should be quite clear that  by SAR they
mean pixel (one of them, not whole picture) dimensional aspect?

Sorry, not read text yet ....
