Yes but they still require BiDi reordering by the layout engine... Something that is not specified by OpenType fonts because it is implicit (and in fact mandatory) for the known RTL scripts assigned in non-PUA blocks. I think you were meaning that those RTL scripts do not require the joining behavior for selection of contextual shapes (and after all this is how the basic unpointed Hebrew script behaves in its usual non-cursive styles : it still requires at least the implicit BiDi reordering by the layout engine, but not by specifications found in Hebrew fonts). -- Philippe.
