> Also IME EVPN is mostly deployed/pushed when clueless app developers expect to have arbitrary L2 reachability across any two points in a (cross DC!) fabric [1], or when they want IP addresses that can follow them around the DC or other dumb shit that they just assumed they can do.

Sorry, but that's really reductive and backwards. It's usually pushed by requirements from the lower regions of the stack, operators don't want to let VMs have downtime so they live migrate to other places in the DC. It's not a weird requirement to let those VM's keep the same IP once migrated. I never had a developer ask me for L2 reachability.
