It's my understanding that weathering steels are avoided for structural applications, since while the corrosion behavior is usually pretty good, it can still be variable and unsatisfactory. There are a few high-profile cases of structures made from COR-TEN and similar that failed due to ineffective patination. It's a shame, since I agree that it does look nicer than most painted objects.

Work has continued in improving the alloy chemistry, so that it can be used for e.g. fencing without creating too many rust stains on nearby objects. One day we may be able to recreate the Delhi pillar alloy.
