There are still applications that break with subnet smaller than /64, so 
all VPS providers probably have to use /64 addressing.

/64 for one customer seems to be too much, on the other side 8 IP's can 
be not enough in some cases. I think 65536 out of shared /64 for one 
server can be enough. You can easily automate provisioning and reverse 
DNS assuming you assign /112 for each server.
If you block SLAAC and provide connectivity to only the static IP's, 
your abuse folks should appreciate it (yes, I know you can spoof v6).
