> **(medium)** Only `treat(Root)` gets a real implementation
> (`RootImpl.TreatedRoot`); all the join overloads (lines 429-450) and
> `treat(Path)` (line 458) just cast and return the same object. That is a
> silent no-op: no type narrowing is applied, but instead of the previous
> explicit UnsupportedOperationException users now get wrong behavior with no
> diagnostic. Could the unsupported overloads keep throwing (or get a
> TreatedJoin analogous to TreatedRoot)?
