Status
Browser bug raised
This issue is applicable to Urdu, Kashmiri, and other Arabic script orthographies.
Languages such as Urdu and Kashmiri are written in a nastaliq style of Arabic, and authors will typically want any font fallback to select another nastaliq font, rather than a naskh or other font.

The GAP
Currently there is no way to tell the browser to fall back to a nastaliq font, rather than a naskh or other font.
Neither Gecko, Blink, nor Webkit support this. Before they can, CSS needs to provide a way for authors to indicate that a nastaliq generic font should be used.
Priority
This is a high priority for languages such as Urdu and Kashmiri, where nastaliq fonts are the norm, and incorrect substitutions may cause readability and cultural issues. It is also a useful feature for other languages, such as Persian or Kurdish, where nastaliq styles may be used for certain types of text.
Tests & results
Interactive test, font-family:generic(nastaliq) will apply a nastaliq font in Urdu

Outcomes
The CSS Fonts 4 spec now defines a generic(ident) syntax which will be used for newly-introduced, and especially for script-specific, generics.
generic(nastaliq) has been added as one of the generic family names.
Browsers are not yet supporting that.
