Yes, I had pushed for this.  I think it would have help better frame this work given how long it is taking.

Yes but had the then I-D been put forward as WGLC, I would have opposed it.  I think that the I-D overstates the case.  Modules have been and do get updated and the idea of having perfection on day is like a frictionless surface, a useful theoretical concept but not one any engineer expects to create.

Dear all,

I am generically not in favor of publishing requirement documents.
However, it might have proven beneficial in this particular case.

Regards, Benoit
