First of all VMAC is a pain on network without IGMP and IGMP can be a =
pain to
implement. So, noone who had to manage VMAC services with high loaded =
server
and mixed routers would recommend it. That is for the poor interest in =
VMAC
on the list.

What in the RFC make VMAC mandatory ?

ARP caching is not a problem because equipments that are doing arp =
caching
SHOULD accept gratuitous arp. For my experience, the one I know do.
