I doubt we'll see any new features on AP2.0 hardware now and, to be honest, this time next year the same will ring true for AP2.5
Remember that AP2 is essentially a different car entirely to a Raven HW3 car -- and there were already significant differences from 2.5 cars. I can't imagine the complexity of developing new features on top of safety critical systems and achieving successful validation, plus meeting regulatory requirements, for hardware (cars) that vary so much in configuration. This is probably partly why Tesla consolidated most build options into just a couple of configs for the buyer... but if I think about the differences between my 2017 AP2.0 car, and a 2019 Raven... sheesh, it's almost an entirely different car - different cameras, different radar, different ultrasonics, different MCU architecture, different Autopilot hardware, different steering rack... it's just a totally different set of parts.
So it's not surprising.
