The functionality doesn't need to (and isn't) going away.

All htdp/testing does is reexport items from the other library, but  
unlike test-engine/scheme-tests it can easily be added by students as  
a teach pack.

If a student does this, and then calls (test) manually; all of their  
test results appear twice. Why is this a desirable behavior to have?  
Why should we be letting students add this as a teach pack?
