Agreed. And that is a reason why it makes sense to have the original
source code compilable (as Etienne raised) -- so basic Java tooling can
still work on the original code even when there are no pre-processor
helpers around (though of course that would be more painful for the
developer).

You can have pointcuts on a whole number of events, including method
invocations but also exception handling, field assignments and accesses,
etc.  But you can only add behavior, you cannot subtract from the
original code.
