User:Cousin Ettolrhc/OP/Non-DWU Category rename

Opening Post
There are many categories hanging around the wiki, such as Category:Non-DWU Cybermen and Category:Non-DWU Doctors, which seem to be attempting to tell our readers that these concepts "didn't really happen in the DWU". The phrase "what really happened" is often used to define "canon", and so having numerous categories about saying "Non-DWU" is arguably in violation of Tardis:Canon policy, which says we do not define a canon.

Solution 1: NONVALID
The prefix NOTVALID is currently used for sources which fail T:VS but still warrant coverage, and I propose we do a similiar thing for these categories. However, I also think "notvalid" looks a bit ugly, and would prefer we did "nonvalid" (a la Tardis:Temporary forums/Slot 6: Subpages 2.0's proposal to have "/non-valid sources" subpage). EDIT THIS IF THE THREAD HAS PASSED AND BEEN ARCHIVED, OR IF THAT PROPOSAL FAILED. This would make the new categories be something like Category:Nonvalid Doctors (or perhaps Category:Non-valid Doctors).

Solution 2: normal, but "from an invalid source" or "from a nonvalid source"
Another possibility is changing the category names to be more similiar to valid categories, Category:Incarnations of the Doctor from nonvalid sources, for example. This has the advantage of continuity across valid and nonvalid pages, but has the disadvantage that the title is longer, and it could be argued that the "nonvalid sources" being later in the category name makes it harder for readers to notice its contents failed T:VS.

Additionally
I think it would make sense to rename the NOTVALID prefix to NONVALID in this thread, as such a minor thing doesn't really deserve its own thread, but I doubt renaming a prefix could be done in a talk page, and this thread is related to that idea.
