WG] My read was that it was using L2VPN's AFI, but defining a new SAFI, so
by strict interpretation, it is a subtype of L2VPN. IMHO it's a bit
hair-splitting either way. The absence or presence of a WG doesn't really
figure into my thought process when it comes to classification, especially
with the overall respin of the WGs in Routing Area, but I'm open to
further discussion if it really needs to be changed.

WG] good to know I was mostly reading this right. The reason that I said
that it inherits 6074 gaps is that it can use LDP. Therefore it won't work
over LDP on an IPv6-only network until the gaps in LDP are fixed, right?
Or is there something I'm missing that makes that an invalid logical leap?

Thanks!
