At the moment, LDPv6 doesn't have what I call "service" support, i.e.,
l3vpn's, l2vpn's, MPLSv6-TE, mLDP, CsC, e.t.c. To be honest, I don't
mind those so much on my end because you can still run a BGP-free core
and still deliver those services.

Granted, if your goal is a single-stack MPLS-based IPv6 network, then
yes, it would be good for LDPv6 to support the "services".

But if it's just vanilla MPLSv6 switching you're after, then LDPv6 will
do just fine.

Well, according to them, SRv6 is winning customers over, and nobody
wants LDPv6. Then again, they have LDPv6 in IOS XR; figures.

LDPv6 must be a business case :-). Well, wonder how they sell so many
CGN's, then :-).
