They might know of some, but I'm of the opinion that it's worth it to support the specification. It only takes one previously undiscovered application to rely on that specified behaviour, and then you need to fix it. If it were solely a game emulator I wouldn't expect this - performance probably comes first... But for running professional software, I'd choose correctness any day. I don't know of any applications the use AF, or the PF result in question, but I haven't looked into it. I'd maybe check some of the big professional things with a lot of legacy history like Photoshop or Excel. As I understand it Rosetta 2 also supports 32-bit x86, not for native macOS applications (where 32-bit isn't supported), but to allow Wine/Crossovers to work, so a whole bunch of ancient 32-bit Windows games might be in scope too.
