There was a suggestion that Latin kerns should be activated by {script,lang}={dflt,dflt}. Let me ask, should Devanagari kerns also be activated by {dflt, dflt}? If not, why?
My own policy is, unless a feature must be restricted to a specific script/language (e.g. a locale-specific feature), all features should be assigned to *all* scripts in the font, including DFLT/dflt, because there is technical reason for doing otherwise and it would help applications not doing automatic script/language itemisation (both OpenType-enabled TeX engines, for example).
That makes much sense (unless a font has hundreds of different lookups for multiple features which could slow down basic processing).
