OK, I should have been more careful in what I said. When I said "no-one
has genuinely suggested", I mean that no-one has put forward a proposal
which has received significant levels of support.
But having said that, some of the examples you list above are actually
positive pieces of information, not denotations of a positive lack.
e.g. maxspeed=no is the same as maxspeed=infinite
drinkable=no is the same as undrinkable=yes
oneway=no might be useful in the very rare case that mappers for some
reason keep marking a road as oneway, but it's actually not! But I'd
expect a note= to be more appropriate. Other than that, I agree it and
noexit=no seem pointless.
