Yes I agree, but which is the implication for tagging?

For me, maxheight=none makes no sense at all, and I would like to
flag that as a tagging mistake in the Wiki, while I have some
sympathy for keeping a record of the absence of restrictions.

A route for a high vehicle is more reliable if there is confirmation
that somebody has already checked the absence of restrictions,
compared to a situation where a restriction exists that has simply
not been tagged yet.

Or should we consider height restrictions as rare enough not to
encourage tagging the default?
