I don't use the site now, but it's almost certainly intended to solve the problem that women get deluged with hundreds of messages a week, making so much noise that it's impossible to not be ignored as a guy, and it's annoying as a woman. In the new framework women can receive as many messages as matches, like a rate limiting, which might make for more participation. I don't think it'll have any more of in impact on the primacy of physical attributes, because those already deeply mattered.
