All this document says is that when Android goes to sleep, it calls
onPause(). But that does not tell what ELSE Android does when it "goes
to sleep".

For that matter, the same doc says that onPause() is also called when
another app takes the foreground, so the application developer cannot
even rely on a call to onPause() as a sure indicator that Android is
going to sleep.

Now I realize that the details of what it does when it goes to sleep
and wakes up might be subject to change w/o notice, but even so, it is
easy to see that the developer often needs to know more than just what
that one doc says about sleep and onPause(). A developer also needs to
know, for example, that Alarms are still checked while the phone is
asleep, and can wake up the phone.
