Fragment combiner programs not supported?

OpenGL OpenGL: Advanced Coding
1

I’m testing fragment programs with NV_fragment_program extension.
Color fragment programs are working well but combiner programs don’t seem to work at all.

For example, even this very simple program doesn’t run:
!!FCP1.0
TEX o[TEX0],f[TEX1],TEX1,2D;
END

LoadNVProgram is returning an invalid operation.
There is no error string returned.
Error position is zero.

System spec:
MSI GeForceFX 5900 128Mb
Detonator 45.23
AthlonXP2000+
WinXP SP1

Fragment combiner programs have been removed from the NV_fragment_program spec but the extension specification on SGI’s extension registry has not been updated yet.

Get the latest version of the extension spec from here: http://www.nvidia.com/dev_content/nvopenglspecs/GL_NV_fragment_program.txt

Ok…
Well this feature looked like a dirty trick but I like those.
I guess this means that combiners won’t be supported in future hardware…
