"Implied appearances" is referring to what Chubby Potato brought up in #77. It bears no resemblance to the situation you just described.

To address your example, though, under CzechOut's proposal, the Dalek spoke new dialogue, so it appeared. It did not appear on the cast list because the director provided the voice.
