If you are talking about consumer CPEs, you certainly can.

Please be more specific. What doesn't work that you want to work? And which of
those things will not be addressed by homenet?

If you're talking about enterprises, I don't see that. (Unless enterprise
network managers are as stupid as Buridan's ass*, that is.)

Well, enterprises or campuses that run DHCP for v4 and SLAAC for v6 are far
from unknown. But yes, exit control is desirable, so most likely DHCPv6
will "win" in a large part of the market.

It isn't. So what? If that's your requirement, run DHCPv6. Your Android users
can complain to whoever it is that supports Android.
