Does anyone use anycast DHCP service?

I think you are not talking about wireless services with roaming.

Then, as you can identify your customer with the authentication
information and can have a static mapping for customer
configurations, you can run multiple DHCP servers without
worrying about dynamic state synchronization between the
servers.

As a malfunctioning anycast server can still advertise a route
to it, blocking routes to back up servers, you should not use
anycast.
