The prize for going to Classic tab is to be Classic enabled. If Hosted was given the same benefit there would be no incentive to continue development and try for a finished server.
Hosted only means they have a small glimpse of what is to come as long as they continue to develop. It is not just for criticism but to possibly gain interest by other developers to come work for them.

I personally have seen Hosted servers that had a small but steady playercount not even attempt to finish their servers since it was good enough in their eyes. If it were also free to play that would make even more servers not bother to try.
