Alright, to dive into the whole lot of discussion:
-Sounds like we're all in favour of keeping the standard amount of energy recovery by Chill.
-Chill disruption has continuously been mentioned as a balance factor, but the problem is that, if we were to truly use it for that purpose, it would have to become a more widely known thing. As it stands, the only people who penalize Chills performed in adverse circumstances are the ones who were around when Negrek gave that negs say-so or somehow came up with the same idea all on their own, which would be rather rare. As it stands, quite a few referees aren't familiar with the prospect of Chill disruption, and more to the point, even less players are familiar with it, which means they won't think to disrupt enemy Chilling strategically. So, if we're going to officially make Chill disruption a factor of balance, it needs to be as well known as Chills themselves are, and possibly even enforced (not by hard numbers or specific situations, since neither would properly account for the vast breadth of ASB circumstances, but it'd have to become the norm rather than the edge case to penalize Chills in the right circumstances).
-I suppose most are in agreement that Chilling should be impossible to a Pokémon who is incapable of using another move due to paralysis, confusion, or attraction.
-On general sleep: I'm so far neutral towards banning Chills from regular sleep, but note that it is very possible to justify flavorwise. All non-Rest sleep is caused by an enemy action, and believe me, falling asleep due to sniffing mushroom spores will not leave you refreshed and full of energy when you wake up (I mean, not that I have personal experience with it, but you know). Note also that Sleep Talk is also always a possibility erstwhile asleep, so banning Chills from it doesn't necessarily strengthen sleep as a status condition too much, since you're not exactly, as has been said, vulnerable or unable to act at all (and in fact, Sleep Talk is so common in ASB, I've already basically trained myself to see sleep in ASB as the status condition that makes Pokémon use moves randomly).
-Rest has been a weirder case in the discussion. Firstly, I think it'd help to clarify things that whether Rest heals all at once or gradually is a matter where the official effects on old ASB have changed pretty much back and forth, so which one a referee does at the present moment is essentially a mark of when they started reffing, which is why there has been confusion about which is supposed to be done. On the more, energy cost all at once and healing gradually sounds nice to me, and it's not that hard to pull off flavorwise either...
-Lastly, I suppose the discussion on Solar Beam/Giga Impact wasn't entirely clear. Chilling while charging a move or recharging from a move is not permitted at the present moment. The matter of fact is that these moves can be used in one turn, but at a higher energy cost; however, Chilling in the action immediately following the move essentially proves itself a means of using the move in two turns while spending less energy. Of course, it's not entirely certain that this is a problem at all, but still, if it is one, then it'd be that one (and I for one already make two-turn attacks cost less in the very rare event that someone actually has them performed in two actions, so although using the move and then Chilling is still probably most energy-efficient, the margin of difference would be rather thin in my own calculation notepad...).
