[Facts] Re: What about Talysh (Iran), Tati (Iran), Gilaki (Iran), Shan (East, North Myanmar), Tai Lue (South China, Myanmar, Laos), Tai Nuea (South China) usage?
Typically I wait for names to be added under a usage before creating a new category for one. You can type freely into the usage field, so just enter "Talysh", "Tati", etc. I'll keep a look out for unrecognized usages and add if necessary.
