Generally OpenStreetMap data is not updated frequently enough by mappers
and database users for us to map temporary states (e.g. anything which
lasts less than 6 months). Many database users will download a data extract
for offline use and only update this every 3 months or so - see Maps.me for
example, and perhaps facebook's  use of OpenStreetMap data.

And most objects in OpenStreetMap are currently only checked and updated
once every few years.

Perhaps someday the community of mappers will be vibrant enough that we
could imagine updating tags every month or every week, but at this point
such a situation is very far away. So for now we should encourage mappers
to focus on permanent or semi-permanent characteristics which are unlikely
to change in the next few months.
