What's the end goal here?  Charge extra if I'm connecting a TV instead
of a light bulb?

I'm not convinced that expected traffic profiles are the right answer.
We already have that in the server hosting market, and it does
constraint the types of services you can run on hosted servers (for
the hosting providers who does this).  I'm wary of the network putting
severe constraints on application architecture, way beyond what is
dictated by current technology.  NAT more or less killed servers on
consumer networks, and this kind of traffic profiling has begun to
kill clients on server networks.

Most service providers appear to be struggling to maintain up-to-date
software on their CPEs (and their infrastructure), and following
recommended configuration practices as they evolve.  This does not
give me confidence that they could perform device management at
consumer scale.

Do we know how much the average consumer trusts their ISP?  Would they
want their ISP to control the digital (and increasingly, physical)
doors in their home?  My own outlook is rather biased, unfortunately.
