Because it's not well defined. If you want to define "steep" as
meaning "greater than or equal to 15% incline", THEN it has meaning.
But until then, it's meaningless.

The wiki page for Key:smoothness says "it is clear...that a major part
of the community does not like this key". But at least there is some
attempt at a definition of "good|bad|horrible" given here:
http://wiki.openstreetmap.org/wiki/Approved_features/Smoothness. But
IMHO they're still not well defined.

What I mean to say is, unless you can think of a better way to tag
incline=* on nodes, we should encourage the use of incline=* for this
purpose (as opposed to some other tag like inclination=* or
steepness=*, or node_incline=* etc., which would just be silly).
