Thread:Talk:Requests for comment/API roadmap/PATH INFO

It seems to me that using PATH_INFO is going to make things more complicated for clients, as instead of at a low level taking an assoc/dict/hash/etc of query parameters, they have to also take a PATH_INFO value. And while that's not much of a complication (if nothing else, a magic key could be extracted from the assoc/dict/hash/etc), what is the benefit?
