I know edge platforms that work like this:

1. "Shared VLAN between customers, SAVI security for IPv4, drop all 
ethertypes that are not ARP or IPv4".

2. "No SAVI."

So if you chose option 1, to use this platform you have to move to a "one 
vlan per customer" type of deployment, for both IPv4 and IPv6, and use the 
upstream router to handle security. So this means changing the entire 
setup configuration, provisioning, fault finding tools etc.

Good luck finding business reasons to do that.
