Uh, I think I see where the confusion comes from.
This comment in WASTE.h:

could perhaps be construed to mean you should install your own
event handlers.  But in fact, it is WESetEventTarget() that
installs Carbon event handlers on your behalf.  All you need
to provide is an event target.  For example, to let WASTE handle
text input events targeted to myWindow, you would use code like
this:

  err = WESetEventTarget(GetWindowEventTarget(myWindow),
      weTextInputEvents, myWE);

BTW, note that WESetEventTarget() is not just for text input events --
it can also be used to install handlers for command events, or
font panel events, etc., according to the options passed in the
second parameter.

They want to turn it into a one-way flow that they have entirely
monetized. I look at the collective human mind as a kind of
ecosystem. They want to clear cut it. They want to go into the
rainforest of human thought and mow the thing down.
