There is nothing really special about the traction tag that makes it more 
likely that this will happen with it than with other tags. Take the name tag 
for example. If the railway shares a way object with something else, then 
does the name tag apply to the railway, to the other thing, to both? What if 
each of them has a different name?

Almost nobody would accept it if we suddenly had to use railway:name=, 
highway:name=, etc. on all ways just because there are some places where 
people want to tag the street and the the tramway on the same way object.

What you'd need is a solution that works for all tags, not a few tags with 
namespace parts and all the rest without.
