  I would say that the result of your project will be usable even if we 
change our mind.   Once relations have been established, they can also be 
updated by a bot also.

   The current preferred convention is one relation per state, with a 
super-relation for all.  Some people are converting existing road route 
relations, but it takes time.     The reason is to minimize editing 
conflicts across long distances where it is likely that 2 or more people 
will be splitting a roadway to add attributes at the same time.
