No, it is LESS robust, because the client identifier changes when the SOFTWARE changes. Around here, software changes MUCH more often than hardware. Heck, even a dual-boot scenario breaks the client identifier stability. Worse yet, DHCPv6 has created a scenario where a client's IPv4 connectivity and IPv6 connectivity break under /different/ scenarios, causing difficult-to-troubleshoot half-connectivity issues when either the hardware is replaced or the software is reloaded.
