One of us is getting confused here.

NIR does _not_ depend during link time on glsl and vice-versa (as per
above list).

To remove the compile-time dependency, I've spent a fair bit of time
trying to flesh things out. Yet that's not possible without rewriting
substantial hunks of glsl, nir and mesa.

With the above said I'm not sure how I can comment on this. Sorry :-(
