I strongly disagree with your disagreement.

The Introduction in the draft captures my needs very well:

"In some deployments, however, there is a strong desire not to use
Router Advertisements at all and to perform all configuration via DHCP
[RFC3315].  For example, network administration may want to control
all host configuration through a single centralized DHCP service in
order to more closely manage which addresses are assigned and in use."

No. The whole point here is centralized administration which ties in
with various other operational support systems. The DHCP server should
control which default router the DHCP client should use, *not* the
router.
