roobet still feels more casino than sportsbook to me

Same here. The casino promos are right up front and sports takes a few taps to find.

Seems deliberate, they push the casino hard and the sportsbook feels like it gets left behind.

Nobody opens roobet for the sports side

Casino pays the bills, of course it's deliberate

The sportsbook feels bolted on anyway.

That seems deliberate. Casino is the main draw, so its bonus gets the front spot while sports sits behind another menu. The layout also nudges sports users toward the casino offers.
