If you want to play 'fixed' RBY that's what mods like RBYPlus are for, or even Stadium RBY. The default option for the ladder should just be to not change the game, and we shouldn't change it because someone personally likes it with a slight alteration. Keeping it genuine is the most neutral and objective option.
To build off what Golden Gyarados is saying... I mean, Sleep Clause itself is an ARTIFICIAL CONSTRUCT. Nowhere in RBY does it exist. Know why it exists on PS/PO? To make the game way less broken and way more fun;playable, essentially. Clauses are a set of rules everyone agrees makes the game far more playable and enjoyable. Does anyone want to play in a metagame where a misclick can get you dropped? Does that make the game more fun? And all to prevent one strategy in any case.
Yes, a lot of people have been saying that a misclick can cost you a game. But still, a game is usually decided on more than one mistake. If you've already made too many mistakes, a misclick can push you over the limit, or it can make it so you have much less breathing room. But that's in combination with other errors. What other misclick automatically ends your game? And all so what, you can't keep sleeping the same pokemon? Again:Switch the hell out. If you allow your only counter to be slept that's bad playing by you and should be punished accordingly. Not to mention this entire strategy of re-sleeping will fail eventually due to missing.
