I vaguely remember that point 5. has been said to encompass openings that
don't show any specific length, nor show NT pattern, i.e. "residual" openings.
Look at it another way : if the need was felt to say a Precision 1D, for
example, is an exception to 5., hence allowed, it means that such an
opening would otherwise be banned ; this applies to your 1S opening.
Best regards,
Alain.
