You are correct that if you have to carve it up into a lots of VLANs, it would be a nightmare. But Hibernia was a true wholesale carrier providing backbone to clients, not links distributing traffic to lots of user end points.
The fact that there was a "switched Ethernet" commercial service doesn't mean that the underlying transport was really "switched ethernet" end-to-end. Ethernet over MPLS is a VERY old concept (VLL, VPWS, VPLS, lately EVPN), and these days Ethernet over VXLAN is becoming more and more popular (mostly EVPN). A carrier using a pure, unencapsulated, end-to-end ethernet for transport over 1000s of km is (and was for at least 15 years) a disaster waiting to happen. Almost all ethernet services (switched, not switched or otherwise) use some form of encapsulation (IP or MPLS, see above) these days.
