This capability is also defined, "more specific routes" - but no one
encouraged any vendors that I know of to support it - so they don't.  Big
demand?

As opposed to a standard deployment, where the DHCP server provides the same
information to every host on that link ... ???

These are separate problems.
Host configuration vs. first-hop redundancy, and we can solve them
independently.

You say hacks, others see it as relatively-speaking simple additions of more
functionality.
You can define any options you want for DHCPv6, write a draft and get
community support.
I don't see how that ("continuously evolving DHCPv6 hacks") is any better
than what is happening with RAs?

I, for one, am just fine with RAs being the first step - leading to either
SLAAC or (some mode of) DHCPv6 ...
