Yup, highway=incline and highway=incline_steep are redundant. A few
other points re: wiki clean-up:

The definition on Map Features - "Incline steepness as percents" - is
a little different to the details given at
http://wiki.openstreetmap.org/wiki/Key:incline. I.e. "the practical
maximum incline on the steep section" and the use of incline=up/down.
The definition on Map Features should make it clear it's used for
*maximum* incline, or alternatively be up/down.

Also, the suggestion to use "FIXME=check incline" to indicate an
approximation IMHO should be replaced with an appropriate
source:incline=* tag.

Also, incline=* is still mathematically valid for nodes to indicate
the instantaneous incline at that point, so I don't see a problem with
