[Tagging] Road hierarchy

[Tomas Straupis]

All right, let's make it more detailed and more extended.

Now A and C are ways leading into the inner territory of residential
building(s). But A has another important road B getting out of it, and
C does not. Which means A has through traffic while C does not. But
all of them are very minor ways visible as two tracks on the ground.
Way C is used say twice in a week.

Now I would like to skip road C at small scale, but leave A, because I
want to leave B.

Can we agree on some scheme to tag this (do data augmentation), so
that less people doing cartography stuff have to resort to heavy
generalisation operation such as road pruning?
