Well, yes. That's the whole reason we started talking about it when we
were talking about scroll-in-place, which wraps the window-scrolling
functions :)

Exactly that.

Normally, in the Other Editors, PgUp/PgDn do move point: it's things
like scrolling using the scroll bars that does not. I'm not sure this is
so useful in Emacs -- when was the last time you used the scroll bars?
When was the last time you noticed they existed? I could have had this
feature on for the last six months and never triggered it once. :)
