Or do you use  global addresses and just depend on router ACLs to protect things? How close are we to having a central registry for unique local addresses, and will that really happen?

What if you apply to a /48 block as end-user because the management
network is not part of your ISP-related /32 or larger block ?
What if you happen to get that /48 and never announce it to the DFZ ?
Then your attack surface gets very small (but still exists, you'll
need some ACLs here and there, notably your customers having
default-routes to your core).
