Correct, LDP etc. must all be done at IPv4.
That can do the MPLS label bits, and IPv6 can then be carried inside
MPLS.
If you use 10.0.0.0/8 for numbering your point to point links, you get
4-8M links, dependant on whether you do /30 or /31.
I don't imagine that represents a problem for many people.
