How reliable is that the Buddha actually spoke about supernatural powers?

In some sutras from the Pāli Canon the Buddha speaks about supernatural powers (Eg here , psychic powers, telepathy, clearaudience, etc). Buddhist masters and teachers nowadays don’t talk about these powers and make me think that in fact is not relevant to talk about them. I also have the thought that maybe not even the Buddha have actually spoke about supernatural powers but were added later to make the teachings more interesting. So my question is how reliable is that the Buddha actually spoke about supernatural powers?
