It will, the built-in hints are only used if no explicit 'root-hints:' 
configuration is defined. So providing non-working root hints will 
render Unbound unable to resolve. Even for configured forward and stub 
zones as priming needs to happen before going out to the network.

Things that don't need recursion will still work like local-zones, 
auth-zones (for downstream only), and rpz (triggers which don't rely on 
recursion) will continue to work.

So not advisable, except for very specific cases.
