Tom, you’re arguing our case.  The requirements specifically state that modules do and need to be updated sometimes in NBC ways.  The idea of this work is not to make perfection the enemy of good.

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

<tp>
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.
