Yes.

It was bad idea, because it made gatewayed multicasts impossible and bypassed routing tables.
Alan, should I restore it? Argument pro: NBMA multicasting is not finished in any case and this thing really will confuse folks, who did not create multicast routes. From the other hand, I think this feature will die in any case and very soon. I'd prefer that kernel did the things, which prescribed by routing tables, rather than making some not overridable hacks hardwired to code.
