Well, to be fair, site's responsibility is to be functional and convenient for the users, so having a feature that allows its users not to use third party tools to utilize said site should always be considered. Easy or not. Platforms like these are not exactly easy to make but they offer convenience, without them the only way for us to be able to have a long distance game with less time restrictions would still be play by email. So, it is a fair suggestion for future feature.
Well, the way I understand it, if you apply to a game and that game goes forth without the GM accepting you into it, they are most likely just deleting your application. So I would be surprised if there are a lot of apps just hanging out there. It doesn't require anyone to withdraw their application. If you applied and heard nothing, then the game was likely filled and the GM discarded extra applications with the click of a few links.
Either that, or the game simply fizzled without actually beginning, in which case you
could withdraw your application, but it's moot anyway.
I'm not saying that this isn't a potential nice-to-have feature (though definitely way down the list of features that would provide meaningful quality-of-experience improvements), but having applications out there that haven't been resolved isn't a pressing systemic issue, and tracking one's own seems like a relatively simple alternative to asking for a new feature.
