+1 As a user, I missed it multiple times.  I would expect deprecation
warnings to show first.  Otherwise, the user might spend their time
learning about something just to discover, at the very end, that they
should learn about and use something else.  That does not make much
sense.

P.S. The *Help* buffer could use more typography and color affordances.
In this case, I would expect strike-through on the symbol name, or the
word "deprecated" displayed in red, or something else.
