Federation Design Plan

Even before that was merged it has been implemented "in effect" because clients like FluffyChat make their own extensions. This is what I mean if Fluxer has some custom functionality it wants, it is not limited by the Matrix spec, it can just go ahead and implement it and other clients may follow or it may be standardized. Either way having partial compatibility with other clients is desirable over none, where we are all playing this game of jumping between different apps and managing multiple accounts just to talk to all the people we want.
