It's quite common when a developer updates a game to remove Denuvo, or when an official Denuvo-free executable is accidentally leaked (as appears to be surprisingly typical), but I don't think it's that common for cracks.
Cracks generally do the absolute minimum to get a game to run, which often means leaving neutered but still performance-intensive DRM in place. Once a game works, I've never seen anyone take a second pass to improve performance. (Games that actually crash are of course a different matter.)
IMO, this is again an indicator of the scene's priorities.
