That also could be optional, automatic host configuration does not 
actually require 64 bits, unless there is a naive assumption that DAD 
need not occur. Which it must always and for many reasons.

rfc3927 does not require 64 bits and works sufficiently well wherever it 
is employed. SLAAC should be redesigned to be configurable to work with 
however many bits are available to it and it should be a standard 
feature to turn that knob all the way from on - off with 128 bit stops 
in between.

And now DHCP-PD can start at any point in the connected hierarchy, 
working with whatever amount of space is available and not requiring 
complete upstream support.

I dont accept that IPv6 is set in stone. IPv4 wasnt/isnt set in stone 
and people were/are actually using it because they depend on it.
