UAVCAN v1.x and CAN XL

I mostly agree. There could be some niche though because where CAN is strong is 1. low cost and 2. simplified analysis of real-time networks (CAN ID arbitration vs. packet switching). But then again, the new low-cost single-pair 10 Mbps Ethernet 802.3cg that happens to support time-deterministic bus topologies might make CAN XL less appealing in some new designs.
