We had the option of NOT adding them to ISO 15924, but then 
permanently "reserving" their codes so that people could use them. 
This is what ISO 3166 does so that people can have "EU".

We didn't think that was better than putting them in the actual list. 
But note that we named them with an initial Z-, which shows that they 
are not really scripts.
