You're misunderstanding the purpose of tagging which is to allow renderers to
differentiate entities & display them accurately & differently from each other.
*All* tagging is for the renderer, it's incorrect tagging that's frowned upon
(natural=sand for golf bunkers is the popular example).
tagging is the description of the geometry, together they form a representation
of the world. Renderers pick those tags from the model in which they are
interested in, and display them as they like.
No renderer has to render highway =track or railway=abandoned or anything else.
It is entirely up to the people making the rendering rules to decide which tag
gets rendered, and how, and when (precedence, stacking order), and whether the
geometry will be modified prior to rendering or will be taken as it is.
Yes I agree.
None of what you said above is contrary to my points, except the
stacking order. Mappers should tag with a precedence, It's already
happening in the vast majority of ways. There's just a few examples,
such as highway=track, railway=abandoned, that cause problems & is what
I'm trying to solve.
