It seems like a very similar mechanism to what is used for defensive ratings could be used for pitch framing.
Zone Rating appears to be fake
Though, maybe that's not the best word. I mean, the hits, outs, etc are all fake too...
Maybe better to say "inferred"

That page refers to setting ball locations on the park, not ball locations in general. They are used in-game.
We do also generate pitch locations, which aren't 100% cosmetic, but would agree they're not really suitable right now for a framing metric.
I wouldn't want to add a catcher framing metric where the catcher literally was given 5% (or whatever) credit for each strikeout, but also obviously I don't want to "lie" in a metric and tell you something that's not true. So yeah, it's a hard problem.
