Owners Pondering Idea of QBs Having Separate Salary Cap

Isn’t the trend towards positionless players? Why not just designate every player on the roster as a QB and spend, spend, spend. What constitutes a Qb? Throwing 1 forward pass, making 1 handoff or “QB” sneak?
I still remember the days when Taysom Hill was taking snaps under center for run plays, and people were getting upset that he was taking snaps from Drew, Jameis, Andy Dalton, and Derek.
