I didn't include that extension because it never became part of any GL 
version.  It's just an extension.  I believe that Radeon hardware 
supports this natively.  Everyone else would need to add a MAX 
instruction in the shader, so nobody ever bothered.  Realistically, it's 
only useful with fixed function.

I don't have a strong opinion either way.
