Earlier I added a tag wiki for [uav](https://robotics.stackexchange.com/questions/tagged/uav "show questions tagged 'uav'") and realised that it would probably be a good idea to add a tag synonym for *drone*, which is the other common term for a *uav*.

Is it better to suggest and add tag synonyms before they are needed, or wait until two synonymous tags get used and *then* combine them?
