The decision to use GLSL 4.00 seems to have been made because of the complex
interactions of the spec:

commit 6f1edf3cbf0ce4cb8e95f2d8bd68c9c26d3f840c

    mesa/st: enable ARB_gpu_shader5 if the reported GLSL version >= 400

    The ARB_gpu_shader5 extension is made up of a lot of small sub-parts.
    Instead of adding PIPE_CAP's for each of these, just rely on the GLSL
    version reported by the pipe driver. The remaining extensions lend
    themselves naturally to being checked through a single CAP.
