oneway=yes for bicycle|foot|other routes to indicate that the signposting
is only easily visible in one direction is stretching the definition of
"oneway", if not wrong.
oneway is an access tag (see https://wiki.openstreetmap.org/wiki/Oneway
where it says "The *oneway* tag is used to indicate the access restriction
on highways <https://wiki.openstreetmap.org/wiki/Highway> and other linear
features as appropriate.") and access tags are about legal access (see
https://wiki.openstreetmap.org/wiki/Key:access where it says " *Access
values* are used to describe the *legal* access...")
Riding a bicycle route against the flow, risking not seeing the signs is
not illegal, it's just less convenient unless you know the route anyway.
I had a quick look at the use of "network=lcn" AND "oneway=yes" on
relations and found it's used a bit in Belgium, some ten cases in NL,
Germany, Austria, one in France, none in Italy, UK, USA
Overall it seems limited in use and could easily be corrected by hand when
a better solution has been agreed.
