I think you're mainly right, although with dynamic library access using
something like  ctypes, it should be possible using just a header file,
not necessarily the lib. (Although with ctypes, as you pointed out before,
this may be a bit slow.)  I guess this mimcs the present situation of
building on a platform with 1.2 binaries but running on a 1.1 platform.

We really should implement some sort of runtime version check to limit the
namespace, at least, because it's rather confusing to have a bunch of 1.2
symbols available when your system is only 1.1.
