Review Comment:
The idea is to be able to check whether all tasks conform to a particular
known parent type. For instance, for changelog tasks we only check if all are
children of `ChangelogScanTask`. Then the reader itself may downcast it to a
particular child type (e.g. `ChangelogRowReader`).
We can't check the type of taskGroup due to Java type erasure.
