Robert, I expect the CE-PE interface, aka VPN service interface, will be implemented between a multiplicity of devices. However, my point was a different one.
Viz, L3/L2 VPNs do not require BGP as the CE-PE interface. So, rather than BGP being a 'non-starter', it is invisible. L3VPNs also support OSPF v2 & V3, as well as others I have probably forgotten. E-VPNs support STP, LAG, LLDP, etc. There are also Pedro's proposal and the IEEE's VDP.
