Exception processing is still a work in process and unchecked exceptions are indeed more user friendly so thought will be needed as this is sorted out
Currently DataSource.translateSql(), SqlSkippedException reference SqlException…

Further elaboration of the error handling system would most likely specify that for database errors the arguments to Operation.onError would be SqlException (or TBD subclasses). Again shows up only as an argument so checked/not-checked is less important. Still the point is well taken.

All the new APIs that I'm aware of use runtime / unchecked exceptions instead of checked exceptions. This is especially true for all the functional/stream interfaces in Java 8, hence things like java.io.UncheckedIOException.
