That much is already the case and doesn't require any change.

Not quite. On the second point, I am implicitly siding with
John and Harald in thinking that it isn't worth writing
another exception into the rule for the CONTEXTO U+30FB,
just to enable it to be used with U+3006 without any
other character.

In other words, I'm supporting the rule as Patrik formulated

For All Characters:
    If Script(cp) .in. {Hiragana, Katakana, Han} Then True;

without adding another conditional to deal with U+3006.
I don't think the benefit for that (allowing use of
U+3006 and U+30FB together in a label without any other
Japanese character present) is worth the additional
complexity it entails for the rule.
