Well, lots of places already have name:la (Latin) tagged, and since it is a dead(-ish) language it often matches the historic name Romans used, but you'll get edge cases like Lugdunum Batavorum which has been used as the Latin name of Leiden since the renaissance, but which is now considered to have been the name of nearby Katwijk. So the tag name:la=Lugdunum Batavorum is correct for Leiden (it is called that in Latin), but arguably not historically correct (it's not the same Lugdunum the Romans knew).
