I dont like the idea of trusting the integrity of every single metal attachment that was made when the building was constructed. They aren’t load-bearing. If they were weak or defective, the only way you’d know is if a strong wind (or an errant climber) caused it to fail.
"Watch a freesoloing climber"
Almost all climbing is free climbing (ie, a rope is utilized, but weight is not put on it to aid in the actual ascent, only in the event of a fall). This was freesoloing.
