Probably, but since we're talking about an Apple product, comparing it to macOS make sense, since they all share the same bottom layer.

Not, probably, that just how any "modern" OS works. It also uses RAM as a cache to avoid reads from storage, just like any other modern OS.
Apple uses it for segmentation and nothing else.
Modern being - since the 80s.
Even on the Atari ST you would use a "RAM disk" when working with "large" data before manually flushing it to a floppy. Some people would use the trashcan icon to emphasise the need to manually flush... Not quite a cache, but the concept was there.
