Sending KYC to any casino or exchange has to be a last resort and only because no other options are available. If I were to use a casino I would prefer to play at one that has no KYC requirement rather than play at one where I have to send it.
I am sure many feel the same way.
In fact there are still many crypto casinos that provides the same 3rd party providers but they do not ask their players for KYC just to play the games. Of course there must be a valid reason why Bitsler decide to make KYC is mandatory for their players in order to play those 3rd party games but I can say that it can be a disadvantage because there are still many crypto players who wants to play anonymously.
This is a guess!Some third-party providers, depending on where they are situated, and the constitution in which they are bounded to comply, which might include having to strictly know who uses their service. (Example: The place where that 3rd party provider is situated have some government policy that will not allow services to be offered to "select-locations", because of whatever special condition yada yada yada.)

It may look like a hassle and disadvantage but as much as we would like to be out of the grip of govts, for us to do what we want, when we want and how we want.
So for players who is okay in doing KYC with Bitsler: aside from the hassle, and having to trust bitsler with some personal information, it would be an advantage if you would like to be sure that the games you played are legal for you, thus you wont be a victim of casinos not giving wins especially "BIG WINS" to players just because they can argue about the legality of playing a certain game.
-So imagine you win 100 BTC on a game by 3rd-Party provider, and you find that your winnings are forfeited because you shouldn't be playing that game in the first place.
-For me that would be a real disappointment.
-Better be safe than sorry.
