[Tagging] Mapping nonexistent paths

Okay, so what *should I propose?*
I'm thinking of making a different proposal that covers the whole
nonexistent issue since my current highway link proposal
itself with this problem and how highway ways that cross each other should
be mapped and tagged.
Should I propose *virtual=**, a new key or do you guys have another idea?
*Some concerns to think about virtual=* and related things:*
- It could unintentionally be added to fictitious elements that have
nothing to do with routing.
- Are these cases for mapping nonexistent features limited to highways?
Are there such things as virtual buildings or other types of areas? Could
we just make a value that could be added to highway elements (like
footway=virtual) so that people don't misuse the key and just use the value?
- Virtual paths might be able to be traversed by multiple forms of
transportation. For example, people and maintenance vehicles can both cross
a sports pitch. Does that mean that this new tagging scheme should only be
limited to highway=path and added access values? Should it *not *be used
on/with other highway elements like highway=residential, highway=footway,
highway=cycleway? Should those be reserved for *real *elements from now
*Other possible tagging ideas:*
- <highway element>=route/virtual (e.g. highway=footway +
