Yeah, that's what I suspected, but only from reading the code of packageDescription().  It doesn't seem to mention this in the docs.  And I wasn't 100% confident from reading the code, in case it was a 'promise' or something like that.

I'm willing to write a doc patch but it'll take a few days, I'm traveling.
