That's certainly one of the original uses, but official_name=* is by no 
means limited to boundary relations. Roads are by far the most common 
kind of feature that get tagged with official_name=*. [1] There's also 
no strict requirement for name=* to be derived from official_name=*, 
though one could argue that short_name=* would be derived from name=*.

In Puerto Rico and some other regions around the world, it's common for 
an urban street to have an unwieldy name memorializing someone as its 
sole signposted name, which goes in name=*, for example "Avenida 
Licenciado Eugenio María de Hostos". [2] Often, locals would know the 
road by a much more practical name that can go in loc_name=*, though in 
some cases they wind up in name=* as well. [3]
