I think our real case is more like - there are fishermans in Philippines that 
will construct the temporary buildings for cargo’s or storages from some 
materials like bamboo, not 100% about the exact usecase here,

estimate the region vulnerability to natural disasters.

I think we can infer it like was mentioned in the previous comments by mark as 
combining temporary=yes and temporary:date_off=never. Am I right?

Got it, will use it further as a guideline, and double-check with you guys if 
there is some ambiguity.

Best,
