You have a point… :-) The wiki already presents the idea that unknown means "unclear". [2]
Taginfo tells access=unknown has 20 thousand occurrences (i.e. 0.30% and ranking at the 11th position), which makes it not so unusual. [3] The discussion here shows the value of "unknown" raises confusion, but admittedly if it was "unknown", "unclear", "uncertain", "difficult-to-tell" or whatever, it will always come down to awareness and getting used to the concept.
