That can be fixed (and I'm sure it will).
"Fixed" in the sense of "work better than today" is not possible, in
Having routers announce their presence makes sure all kinds of
trouble that can easily occur with IPv4 isn't an issue with IPv6.
Look at that, someone bothered to do work on VRRP for IPv6. That
was a waste of time, because router advertisements and dead
neighbor detection give you the same functionality without the
need to configure stuff.
RA's are great in certain situations, and I use it on some subnets but
we must have a full set of tools that work with RA turned off.
There are situations where I cannot have hosts (servers in particular)
autoconfigure addresses or gateways, even accidentally.
Then they shouldn't listen to discovery protocols such as RA but also
DHCP (and VRRP in the sense that you were suggesting although VRRP
isn't designed to be that).
I'm not sure what implementations will do when a statically
configured default fails (succeeds?) dead neighbor detection...
