I don’t think it’s required, but my friends who do flights for remote mining operations in SE Asia use the same concepts — so it really is pretty standard for commercial flying, even down to remote private operations.
A bad bump on a commercial plane can be hundreds of thousands to millions in damage + downtime + inspection/repairs. And tens or hundreds of millions if you wreck a big plane. Companies may be evil, but most would still prefer you waste $2k in go around fuel than $200k because you decided to set it down badly or $20M+ because you drove their plane off the runway.
