The only disadvantage of this approach is that you waste up to 75% of

want to do some really weird things you could configure mismatched
subnet masks on servers and routers, use host routes to point toward the
servers ... This will reclaim almost all the address space, but result
in somewhat more complex addressing and routing.
It's not weird.

If you do it like that with local-proxy-arp then you can have multiple
vlans per IP subnet, so you get L2 isolation between customers but you do
not waste any IP addresses.
