More than 256 subnets in the home? Who would want to manage all of that?

I can't see more than about 16 subnets at a single residential
address with a single family and would suggest a /60 by default 
for "bog standard"  residential customers, with a /56 possible 
if they ask nicely. Every subnet represents a management burden
for the end user, if a genuinely separate subnet is required.
