So, you think it would make sense to add s-s to quz but not the rest? (I'll keep that in mind the next time you want to encode characters to complete a paradigm.)

What MS has implemented used the tags quz-BO, quz-EC and quz-PE, which are the tags that follow the recommendation in 5646 and that you yourself gave: don't include script subtags (quz-Latn-BO, etc) because that would be redundant and unnecessary. But the registry does not capture the fact that that would be redundant and unnecessary because the record for quz doesn't include the s-s field. Now when implementing software that would compare tags, whether the tags are parsed or not, we need additional data indicating that quz and quz-Latn are to be treated as equivalent, and likewise for quz-BO and quz-Latn-BO, etc.

I don't want to add subtags: I'm not asking to add subtags in the registry, and I don't want users to include the Latn subtag in tags based on quz. The most reliable way to effect the latter is to add a s-s field to the record for quz so that the data in the registry reflects what we here know: that a Latn subtag would be redundant and unnecessary when used with quz. (And likewise for the other cases I've mentioned.)
