True, but it's complicated...
Looking around https://msdn.microsoft.com/en-us/library/windows/desktop/ff476876(v=vs.85).aspx
you can see that feature level 9_3 e.g. mandates support for max
texture size >= 4096, which is only guaranteed by SM3-level hardware
(https://msdn.microsoft.com/en-us/library/windows/desktop/bb219845(v=vs.85).aspx).
IIRC there were a few of those, which is why I decided to require SM3
for 9_3 even though the shaders themselves are going to be SM2 only.
