More to the point, how does software render a soft hyphen included in
inserted LTR text, when the outer text is Hebrew? Would it always be
ignored? Would it be rendered? How?

Mind you, I don't think that the bidi algorithm as such needs to care
about these details, but the Unicode Standard does mumble about
different conventions. Might be useful to add some examples to such
mumbling.
