The reason tends to be "only planning on adding to driver that supports version
N, don't feel like thinking about earlier versions". In general, we disregard
those where they don't make sense.

A test that requested a compat GL 3.2 context would likely have similar issues
to what you're seeing now with Mesa.

(All that said, ARB_gpu_shader5 should probably not be exposed in a GL context
below 3.2 on Mesa -- it could potentially work with lower with
ARB_geometry_shader4, but that's not supported in Mesa.)
