BTW, if you want to look at this from the router administrator's perspective:
Configure the router to send the M flag set in routing advertisements for a Link IF: 1. A stateful DHCP server is deployed for that link (either on it or reachable via a relay agent) AND
IMHO, you're making a significant leap of faith in assuming that whoever configures the router's M-flag advertisements has sufficient clue to grasp the different semantics that arise with:
- M-flag and/or O-flag - stateless and stateful clients - stateless and stateful servers - stateless and stateful relay agents
Hence, if we want to build a robust system, we need to design it with care.
