As far as I know, everybody who presented "documented need" *did* get
their blocks.  At least, this has always been the IPv4 policy as soon
as there was space to allocate - and there has never been a clause "for
this-and-that access technology, you can't have space".  Neither for DSL,
nor cable, nor for mobile.

If mobile providers decided to not follow this route because they found
it too complicated, or too cumbersome to document what some considered
trade secrets and went with CGNAT instead - that's certainly their own
decision, but was never mandated by policy.

I don't agree that it is the APWG chair's decision which request needs to be backed by facts and which isn't.

Since you've run an IXP yourself in the past, you should know the 
technical requirements quite well.  So I'm not sure exactly what point 
you're trying to make.
