Stop trolling and move on. FAA expects FAA-approved company procedures to be followed. In this case taxiing without final weights is an FAA-approved procedure. If an overweight taxi occurs that’s a (relatively) easy maintenance inspection and happens so infrequently it’s worth the 99.999% of times the procedure works well. The company knows all of this when they write procedures and the FAA knows all of this when they approve the procedures.
