the assumption made in RFC2461 is that the link MTU is constant

MTU negotiable between peers, it would complicate too many things.
FWIW, I agree with this assumption. Really, if you want to put different MTU's on the same link and want to optimize it, use multiple links..
We must face facts that there are multiple access, shared-media links out there and will continue to be for the forseeable future. We can wish for a densely-connected mesh of point-to-point links (e.g., ATM PVCs) but we needs-be have to support the L2 infrastructure that is already deployed. (Otherwise, we would have to go through an L2 transition before we even begin to tackle the IPv6 transition.)
