LAB, I personally would never express it the way Sam did, but at least one of the meforshim claims that the Ra’avad did indeed misunderstand the Ramba”m. Of course, the Ra’avad disagrees.
The Ra’avad himself seems to admit (at least this is how I understand his concluding words) that his pshat will not be entirely satisfying to everyone.
The meforshim I’ve seen on the inyan (admittedly only a few) seem to take the approach of explaining (and I assume, agreeing with) the Ramba”m.
