Yup, but 1) this change will be visible during emerge -pv since new
linguas value are visible there, 2) we already have gettext packages
with linguas supported.

Thank you for suggestions! Actually it was just an illustration loosely

I see.

But what is preferred way for gettext packages? Define supported
languages in IUSE or use strip-linguas if required?
