Speaking of Sleep Clause, did I mention that implementing it through a system of courtesy on Wi-Fi would be a major pain in the ass if Starmie and Blissey had more viable alternatives to Natural Cure than what they have now? You'd basically be forced to give away your Pokémon's ability before the match so that both people can keep track of Sleep Clause.
Bottom line, Shoddy doesn't follow Wi-Fi (or PBR for that matter) perfectly already, and in every case it's for the best. Besides, two other things: first, the glitch's behavior is so odd and necessitates so much research that it'd be hard to get it down perfectly, and second, if that glitch occurs on real copies and not just bootleg ones, the US version is coming out in less than two months, and there might be a fix for it similar to the berry fix in Emerald.
Edit: One final note: there's no uber rule on Wi-Fi either, and while I'm not fully aware of PBR's rules when it comes to that, we've seen all of Nintendo's attempts at defining what's uber or not become the target of much ridicule. No one outside the competitive community would ever think of Wobbuffet or Garchomp as ubers.
