Right. Actually I have not tested whether iText properly excludes your additional exclusion range but Adobe Reader definitively does not accept signed ranges with exclusions other than the signature container.

Obviously. But those unsigned attributes cannot be mis-used to make the document appear different (at least that should not be possible). Unsigned parts in the PDF on the other hand might be (unless an individual in-depth analysis proves the contrary) and, thus, should not be approved of by PDF signature verification tools.
