Sounds similar to Infiniband where each subnet has a subnet manager which calculates routing tables for the entire subnet, and assigns 16-bit local identifiers

Sounds similar to Infiniband where each subnet has a subnet manager which calculates routing tables for the entire subnet, and assigns 16-bit local identifiers (LID) so you stations don't need to use the full 16 byte GUID's.
Also Infiniband packets are power of two sized, making fast switching easier.

When Ethernet was first released, compute was expensive. Made sense to centralize compute (in routers) and make everything else dumb-tolerant. Now, compute is cheap and plentiful at network-calculating scales and throughout expectations are very high, so it makes sense to burn compute (including in clients) to simplify routing hardware.
