The wiki for conditional restrictions gives the following examples:

  - oneway:conditional=yes @ Su described as "Street is oneway on Sundays"
  - motor_vehicle:conditional=no @ (2018 May 22-2018 Oct 7) described as
"Section of road is closed for motor vehicles for a few months (for
construction). Navigation after the end date should work even for maps
created in the meantime."

In my own mapping I have a street that's normally twoway but has been
oneway due to construction for over a year, with no firm end date.
Following the wiki's examples I could tag it as "oneway:conditional=yes
@ (2019 Jan 1-2020 Jan 1)" and monitor the situation, updating the date
range as necessary and eventually removing the tag. But my understanding
of best practices for conditional tagging is to tag the most restrictive
value first, and add the less restrictive value to the conditional clause.

For now, because I don't actually expect any data consumers to parse the
conditional, I simply have it tagged as oneway=yes with a fixme. I
suppose there'd be no harm in adding a "oneway:conditional=no @ (2020
Jan 1-2999 Jan 1)" and updating the start of that date range as new info
is available... but it seems a little silly.
