Yes it's, and many sources need setup after connection and before can be
used properly.
Not all databases support that setup via connection URL.
Ex. SET ISOLATION LEVEL , COLLATING , CLIENT ENCODING, etc.

This way don't have restrictions to do anything you can do via direct
jdbc but inside H2.
DBLINK as a datasource bookmark on H2 that can be activated or
de-activated as needed or on access sound very promising.

This is a plus , I had not thought of that.

DBLINK could implement a  getConnection() method to open the door to use
many wonderful H2's tools over external data too ( Csv , RunScript ).
