Timeline for Will Ethernet standards ever be updated to not require MAC src/dest to be included in every frame since the switch can keep track of it?

And Ethernet's success is largely due to its simplicity and universality (along with low cost). Different host and interlink protocols would kill that. | |

However, assuming that wasn't the case. The expectation is that sources would only need to tag the dest address on each ethernet frame since switch could fill out the src (again assuming one MAC address per port) | |
