Thread:User talk:CodeCat/sort key

I have added a sort_key for Armenian to Module:languages. How do I make use of it from Armenian templates such as ? On a related note, I am thinking of orphaning all Armenian headword templates and migrating to, since covers all their functions (assuming autotranslit will be added to it soon) and has some additional goodies. Is there a reason we encourage languages to have custom headword templates? 90% of languages need very simple headword lines and does the job.
