That would be an entertaining support phone call with grandma.

So, she gets a new CPE which issues 192.168.1.0 to her laptop and .1 to 
her printer, and then her printer can no longer talk to her laptop.

I'm sure that the ISP would be happy to walk her through doing a 
firmware upgrade on her printer or that her day would end up better for 
having learned about DHCP assignment policies on her CPE.

They could even email her a copy of the RFC and a link to the IETF 
working group if she felt there was a problem.
