Well, I guess we fundamentally disagree on that point.

I gather that it is "Zinh" that you consider to be twisting ISO 15924, but it is not BCP 47 or its users that requires "Zinh". Rather, it is the Unicode Standard, which is closely aligned with ISO/IEC 10646; and while ISO/IEC 10646 isn't today making reference to ISO 15924, it continues to align more and more with the Unicode Standard and, in particular, to incorporate data files that are part of the Unicode Standard; and so I would not be surprised if, in the near future, ISO/IEC 10646 also require "Zinh".

I'd agree if the audience for those special-case codings were limited to a restricted audience. IMO, however, Zihn is not. Effectively, via Unicode it will be used in the vast majority of information systems that process text.
