This is exactly my point.  It is unexpected (at least to me) when it is
necessary to look up a way to understand a tag on a node.  To me a node
can not have an incline.  One could model this with a relation saying
that this way has an incline at that node.

Are there any other "official" node tags that depend on a parent way to
be fully defined?

There are close to 1000 nodes with a oneway tag according to osmdoc.

There are also some oneway tags with some rather interesting values like
"-1; 1; 1; 1; -1; -1" or "yahoo".

Anyway, I would like to add a note to the 'highway=incline|incline_steep'
tags on Map Features saying that they discouraged in favor of
'incline=*'.  I think there should not be redundant tagging schemes in
Map Features.  I would also add the values 'up_steep' and 'down_steep'
to 'incline=*' for this to be a equivalent replacement of the highway
tags.

I would also like to change 'incline=*' so it does not apply to nodes
anymore.  But, if there are objections I will hold off on this one.
