I have never been a proponent of BIP 38 (which this BIP is derived from) and generally think that encrypting a secret with a human generated password is silly for many reasons (Let me know if I should repeat my list of concerns). As far as I remember we are pretty much on the same page here.
Using SSS is superior in every way that I can think of.
