Oh boy! A consipiracy theory!

Incorrect. In the first place there are several of these "special"  
tags registered already:

Zinh
994
Code for inherited script
codet pour écriture héritée
Inherited
2009-02-23

Zmth
995
Mathematical notation
notation mathématique
-
2007-11-26

Zsym
996
Symbols
symboles
-
2007-11-26

Zxxx
997
Code for unwritten documents
codet pour les documents non écrites
-
2007-06-13

Zyyy
998
Code for undetermined script
codet pour écriture indéterminée
Common
2004-05-29

Zzzz
999
Code for uncoded script
codet pour écriture non codée
Unknown
2006-10-10

Some of these were used in Unicode, and have, in the field before the date, Property Value Aliases (Inherited, Common, Unknown). The script property previously used two Private-Use codes, namely Qaac for Coptic (now replaced by Copt), and Qaai (now replaced by Zinh).

Kindly do not shout.

As Registrar of ISO 15924, I should like to point out that we have a committee that decides these things, which includes people who are not members of the Consortium.

As I recall Mark Davis proposed Polytonic Greek and IPA to be scripts in ISO 15924, and these proposals were rejected in favour of subtags here.

Zinh was accepted on foot of the arguments put forward for it.

Please do not.
