OK, so it remains the same: there is an interest to know whether it is
a residential street or a small one in a "not-residential"-area.

the problem is, that it is far more timeconsuming to check this for
all roads instead of having the information already avaible as such.

well, tag whatever you like, I just can tell you, that the definiton
in the wiki says for residential, that there must be at least at one
side residences. If you don't care about this definition, do as you
like. You'll IMHO loose a datum and gain nothing.

but I guess you won't find an industrial zone with very narrow streets
(unclassified, probably you'll find footways and service), while of
course in residential areas there might be wider streets (and often
they won't be residential but tertiary then).

Just for my interest: is any of you familiar with the national/local
planning regulations for roads in your area? Maybe it would help to
have a look if you haven't already done so.
