"The 'naturalLanguage' attribute syntax is a standard identifier for a
natural language and optionally a country. The values for this syntax
type are defined by RFC 1766 [RFC1766]."
Let's consider that a bit: either
- the first clause is only a partial statement of the syntax and the
second clause is the complete reference statement, or
- the first clause is the complete reference statement of the syntax and
the second clause is badly-stated clarification on how to interpret
- the two clauses are contradictory statements of the syntax.
What you seem to be saying is that the second alternative applies.

Ouch. Clearly not an implementation of RFC1766 but rather of something
*like unto* RFC1766.

So, there will simply be scenarios in which content will not print with
appropriate font choices. There is nothing we can do about the reality
that there will be content tagged "fil" or "az-Arab".

Their back-compat story was broken even without infixed script subtags
simply because of their choice to implement 0*2alpha "-" 0*2alpha rather
than RFC1766 and the unavoidable reality of the need for alpha-3
language IDs from 639-2. And they've been broken for around seven years
ever since RFC3066 was published; 3066bis didn't really change that.
All we can do wrt Suppress-Script is some damage control for
high-importance cases such as en-US and fr-FR.
