I don't know SDM, you clearly provide that your ~convenience~ is something you would want to keep.
With that i would go to my initial statement that the rule is void, because there are even more people that are not going to get top stats, are casual competitors, and probably wouldnt want to have to deal with submitting proof for every single green or blue stat they're getting.
Also flimsy, no matter WHAT we do: This is going to be a BIG change for TSC. If we take the rule, we will still grandfather those stats. If we ban emulators, we will still grandfather those stats, since we have no way to prove or not prove most of these stats as emulated or not. You can't really break a law that hasn't existed, so...
All in all, I'm just seeing "I would rather keep emulators for MY convenience sake, because i'm not going to be bothered by the rule." rather than "We want a fair playing field between consoles and emulators." Maybe I really am too biased, but still.
If we're gonna make convenience a thing I'm not gonna shut up about it.
Banning emulators is the only step that makes sense and everybody suffers from it the same. And you gain the fact that inaccurate emulation will never be a thing.
