Exactly, but IIRC we get warnings on packages not listed in Suggests: which are
accessed via '::'.  And that need for a Suggests: goes away for a base package.

Otherwise Peter's reminder is entirely correct. You can do _either_ an
  importForm("graphics", "plot", "legend") in NAMESPACE (which I have done)
or use the explicit
you have.
