Well, sure.  We might just disagree on the definition of "unnecessary". 
  Requiring licensing for a CDM (either a patent or closed-source 
copyright license) from a consortium of your competitors might strike 
some as an unnecessary restriction and might seem perfectly fine to the 
members of said consortium, say.

I don't see what GPLv3 has to do with my example of a custom-built 
device or a new device trying to enter the market.  How does either one 
end up with a CDM in a way that's not open to abuse?  (Note that RAND 
licensing is in fact open to abuse, as far as I can tell, though some 
claim it's not.)

Indeed.

Well, it might insofar as we privilege one or the other set of choices, yes?

I think that enshrining things in de-jure specifications that 
implementations are then expected (and in some cases coerced, by law) to 
conform to always involves a certain aspect of public policy on the part 
of standards bodies...
