Instead of replacing the definition, would it make sense to just add an additional definition so there is two events listed, one fixed, one not? That way a user could pick which one they wanted? I guess on POWER it might not matter, but at least on recent Intel chips it would be nice if we could specify the difference as it turns out the fixed vs programmable events have subtle differences and it's hard to test this as it's impossible to specify one vs the other.
