It would certainly be easier to maintain a 2.2-proxy branch, with the intent of it actually being folded *into* 2.2, if the branch used the same dir structure as trunk, that is, a separate directory that includes the balancer methods (as well as the config magic associated with it).
However, if that will be a impediment to actually *getting* these backports into 2.2, then I'm willing to keep the old structure... So my question is: if to be able to easily backport the various trunk proxy improvements into 2.2, we also need to backport the dir structure as well, is that OK? I don't want to work down that path only to have it wasted work because people think that such a directory restructure doesn't make sense within a 2.2.x release. PS: NO, I am not considering this for 2.2.12! :)
