We want to update our integration to consistently identify archived trailers, and given that there can be multiple Trailers with the same name and the Trailer object doesn't include data to indicate if its archived, our plan in the interim is to look up the matching Device using the 'tmpTrailerId' and check the 'activeTo' date.
How long can we expect the 'tmpTrailerId' property to remain on Devices? Will it be there until Trailers are finally fully deprecated, or is there a possibility the property is dropped before then? I searched around for some official documentation but only found community forum posts with Geotab engineers talking about the property's intended use. I didn't see anything to indicate a timeframe for its inclusion on Devices or whether it's expected to be removed whenever Trailers are.
