hey,
Not necessarily. There are 24 port L3 switches to be had for around 500 EUR that do IPv6 wirespeed L3 routing just fine. You can even do protocol based vlans to do one vlan per customer for IPv6 and have an aggregate vlan for IPv4 traffic.
Forcing network design on people as a workaround is not a way forward. What if the L2 domains have to live inside L3VPN? What if you want to support netflow? There are many reasons not to use such network design/devices.
