Stumpwm can run on different Common Lisp implementations and perhaps not
all of them require cl-asdf to run Stumpwm.  So Stumpwm shouldn't depend
on cl-asdf.  Recommended packages should be installed unless you know
what you're doing, see Debian Policy:

  The `Recommends' field should list packages that would be found
  together with this one in all but unusual installations.

So I'd say `Recommends: cl-asdf' is OK here.  Do you think otherwise?
