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:

…
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 ..)
