Well, OK. 'Classification' then (which gives indications to who can use it).

How are they second class?

This is where secondary tags become useful. If renderers wants to show,
for instance, all paths in one style, they easily can by filtering just
highway=footway* If they want to differentiate different surfaces*,
access restrictions etc, they can do that by referring to secondary tags.
* On a suggestion by Richard Fairhurst the OSM carto now emphasises a
footway if it has a surface=" sub-tag
