I've added conditional access tag to the parking lot, so those renders has a chance for fixing themself at some point and this will work.

Even though I'm still slightly not sure if temporary is the correct key for this, https://wiki.openstreetmap.org/wiki/Key:temporary "mapping temporary features is strongly discouraged". 

This looks like it could be useful in the future, if it gets accepted: https://wiki.openstreetmap.org/wiki/Proposal:Temporary_(conditional)
