Where should an arbitrary client know the best MTU for the network from?
The DHCP server is (supposedly) managed by network administrators, which
should know better. Path MTU discovery can deal e.g. with PPPoE
overhead, but the more reliable choice really is often to just cap the
MTU at 1492. Noone forces the server to announce one, after all.
