One might reserve space (code point positions) in unclear cases, that might be filled in in the future.

The reason they are not present in Persian notation, is that one usually do not transpose, but it is easy to do that in modern music computer engraving programs, so it might be nice to have them for that reason.

I have written C++11 code for an arbitrary number of generators. The traditional staff uses two generator, for example the major and minor seconds (traditionally the perfect fifth and octave). The Turkish, Persian and Arab music requires three generators. In Persian music, Hormoz Farhat, “The Dastgah Concept in Persian Music”, uses a neutral second for that description.

Right. That’s why I cc’ed some experts.
Personally, I prefer the Extended Helmholtz-Ellis JI Pitch Notation, which does not have those limitations.
