We never roadmapped dropping WIndows XP. That still has more users then
10.7 and 10.8 combined judging form our google analytics.
10.9 will soon be dropped from the official support roster by Apple.

It is not just about that. Most compilers and other packages are defaulting
to it. Compiling binary python stuff for use with the official blender
makes you jump through more hoops then most people can. Not many people
have a version of python compiled with msvc 2013 on windows when it is
officially deprecated and the official python release is with 2015. A
similar argument can be made for almost any package for python that
contains native code on MacOS they all use libc++ as that is the default.

Sure. release is not build on a machine that is kept up to date. It is
build on OS X 10.9 with code 6.3 and a clang version compiled by Jens.

Yes, we can also have windows XP and windows ME, 98 support. it is just a
question of adding some extra hands. If we care about user numbers we might
want to port to android soon.
