Or is it that you want IPv6 to be a 128-bit version of IPv4?  


Yes, this is in fact exactly what the network operators keep saying.  

RA is a
good idea and it works.  You can add options to DHCPv6, but I don't
see many vendors implementing default gateway support unless you can
make a real case for it.
My fear is that your goal is to do away with RA completely and turn to
DHCPv6 for all configuration.  RA is actually quite nice.  You really
need to stop fighting it, because it's not going away.

RA may be quite nice for some cases.  However, several examples over this thread alone have been provided about some 
other cases where it is something other than nice.  

DHCPv4 is not a perfect protocol, but it's widely deployed and understood.  It also is a one-stop-shop for centralized 
host configuration.  IPv6 does not currently have a similar one-stop-shop protocol, and this is a major gap in 
functionality.  There are a bunch of very large providers and enterprises which number their DHCP-managed end-sites in 
the hundreds of thousands or millions.  The inability to provide the same centralized configuration management should 
not be considered a feature.
