From Tardis Wiki, the free Doctor Who reference
Categories for stories by companion will not be created (bar the exceptions mentioned by User:CzechOut). Categories that have already been created will be removed.
The reasons for the decision are simple and are as stated in CzechOut's post: the technical reason that SMW is the preferred way of collecting and using this info, and the administrative reason that we are trying to avoid category bloat.
(Incidentally, if someone wants to find stories by a certain companion, it's more likely they will use the appearance pages, which most companions have.)
