Sending hostnames isn’t required for DHCPv4 either. If we want to talk about ill-behaved clients, I don’t see why you can count this as a negative for mDNS but not stateful DHCP.
No. mDNS is not mandatory (e.g. my TrippLite UPS management card doesn't support it), and it requires active device participation. If a device is busy or slow to respond, you'll miss it.
DHCPv4 leases are authoritative, and they don't require device participation for discovery.
