Here's my opinion on the matter, but I'd like to hear from Brian or Keith.
1. All drivers should expose GL_ARB_vertex_program and
GL_MESA_program_debug. I don't care either way about the NV extensions.
So you think we should announce it even though the spec says OpenGL 1.3
and 1.4 are required? Maybe Brian can tell us why he thinks that
GL_MESA_program_debug needs 1.4.
Mostly that just comes from re-using boilerplate from other extension
specs.
If you want to be pedantic though, fragment programs have an
instruction for biasing the mipmap levels used for texture filtering
which has some interaction with GL_TEXTURE_LOD_BIAS, which was added
in OpenGL 1.4.
That said, the vertex program extensions can probably be used just
fine with OpenGL 1.2 (or perhaps older).
