well, only for gsub, not for gpos where only arab/dflt is defined

Are you saying that is a bug with the font? If so, I could report it, for what it’s worth.

Tried to look into the spec regarding GPOS lookups: https://www.microsoft.com/typography/otspec/gpos.htm

<quote> …

To access GPOS information, clients should use the following procedure:

1. Locate the current script in the GPOS ScriptList table.

2. If the language system is known, search the script for the correct LangSys table; otherwise, use the script's default language system (DefaultLangSys table).

yes but for testing and control i don't like hard coded defaults so that has to go via an option; a next version will have a 'default' option that when set to true will fallback on dflt .. and tex is about control (btw, features and what should be on/off are the messiest part of opentype ... and often very inconsistent so ..)
