Agreed. They've also been extremely finnicky from my experience - had cases where large EVPN deployments just blackholed some arbitrary destination MAC until GARPs were sent out of them.

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.

VXLAN is used in cloud/virtualization networks commonly. VM HA/migration becomes trivial with VXLAN. It also replaces L3VPN/VRFs for private networks.
