"At least Islam has significantly narrowed the scope for belief in supernatural entities". I think looking at it this way misses the point; superstition is not defined by belief in the unseen, it's defined by evidenceless apprehensions. So for example there is nothing superstitious about belief in the Jinn or 'ayn, as this is entailed by rational belief in the prophethood of Muhammad ﷺ.

I was not equating superstition with belief in the unseen.
