So basically, you have to decide that all unknown values default to
either one or the other.

If I'm a renderer, and I come across bicycle=difficult, and I only know
about "no" and "yes", which one do I assume?

IMO, at the very least, people who wish to extend existing tags in this
way need to update the tag description page to say what the default is
in the case of an unknown value.
