When you have people complaining about too many rematches this argument loses it validity.
No, it makes sense. They already continue booking the same guys every week, running the same matches, keeping guys off TV. With no brand split, they'll have even less of a reason to change things and guys who were getting crumbs of TV time won't be able to lick the spoon.
With all these useless shows, they're better off going back to brand-exclusive PPVs. It will incentivize them to try harder with weekly shows, get more people on screen, and they won't have to worry about getting everyone on the card anymore.
