Thus such are the benefits of having over 13million exp in a stat. Also, that prayer bonus you mentioned earlier, only applies if the user has two or more stats that are level 99. Based on the conditions that I mentioned earlier, a F2P player that kept their skillcape would be discouraged from bringing it into BH, because he or she would be unable to purchase it again until renewing their subscription. Now, as for members bringing in skillcapes into F2P worlds, they will most probably be in either the Mid Level Crater, or the High Level Crater. Now, in P2P, how many people do you see bringing in skillcapes? In F2P, since the profit there is minimal, thus there would be even less people with skillcapes(It can be assumed that most skillcape owners are higher level more experienced Runescape players and prefer higher stakes). Either way, I can't see anybody being greatly affected by making skillcapes wearable items in F2P.
