The FA owner does have the right to add protection if he wants. I too laud him for bringing this up for discussion. I say go up there with one of your closest climbing partners, have them lead it and ask their opinion.
I think though that if you did add a bolt or two, you might regret it later on because it could spoil your previous accomplishment. Think about it, try it again, wait till the end of the summer before making a decision.
