The benefit is in greater accuracy and completeness.  If we can do 
better than commercial street directories, then why not?

To my mind, it's a bit like deciding whether to make a minor road with a 
concrete dividing strip a divided road or just a two-lane, two-way 
single road.

Insisting that everyone do it that way would be a pain.  But if the 
information is available then I see no problem in my capturing it if 
convenient.  Nor to I see any pain caused to the user of the more 
complete maps.

And you never know when accurate information might prove useful.
