The most impressive part of Control's RT (on PC at least) was that it very much applied to (most) dynamic objects - and it features a TON of dynamic destruction.

The "office building" setting meant resticted areas, sure, but it features TONS of reflections - especially transparent reflections (which are practically impossible to decently approximate with screen space techniques).

Oh, and: The Northlight Engine already did more than most other engines at the time to get "90% there" with a ton of hybrid techniques, not least being one of the pioneers regarding realtime software GI.

The other elephant in the room is the consoles, and even if they're capable of RT they also have to consider the performance capabilities versus visual payoff. As I see it the PC versions of games like Control from studios like Remedy are trailblazers, it's an early implementation (geforce 20 released in 2018, Control was 2019) as the ultra option to shakedown their implementation and start iteration early so future games will benefit, however the baseline is non-RT.
