Quick question regarding R "basic" biz-class fares OneWorld Ruby Status: If I book a large party (6 pax, 2 adults and 4 kids) will my OW Ruby status let me pre-select seats for the entire party?

I know the OneWorld site lists "Access to preferred or pre-reserved seating*" as a Ruby benefit, but I'm not sure what that practically means (if anything) with R fares on Qatar.

Followup question: is there any indication or informed speculation whether or not R-class will affect stopover hotel benefits if/when those come back?
