LGTM! Thanks for adding this feature
Could you add an integration test against the iceberg-rest-fixture? Currently http://localhost:8181/v1/config returns
"overrides": {
"namespace-separator": "%2E"
},

The REST spec currently uses %1F as the UTF-8 encoded namespace separator for multi-part namespaces.
