The beauty of the concept of the backbone network with PoPs is that every user can select the VPN protocol that they like (from the protocols offered by the PoP) and that not everyone has to use the same protocol. Some people may like OpenVPN because they know it, others may prefer L2TP/IPsec because their router supports it, others may want to use wireguard or openconnect.
Of course it will not be possible to offer everything invented in the world and still keep it managable, but at least there is no need to agree all on using the same protocol as there is with the IPIP mesh. We can add new protocols as they become available or become more attractive due to changing circumstances (e.g. support IPv6 both on inner and outer address, independently of course).

If we will be connecting to the POP via VPN, I would highly recommend Wireguard instead of OpenVPN. OpenVPN is kind of slow. Kun
