I agree with this 100%. I think this should also cover comic book adaptations or "prequels" to upcoming movies as those prequels don't always end up fitting when subsequent movies are released. (The X-Men movie prequels, the more recent Prequel comics to Captain America: Civil War will likely not stand up once later movies are released)

Another point of confusion is that some video games have started using canonical reality designations and, of course, these video games are almost never accepted into the cannon. (The biggest one that comes to mind is the various Spider-Man games that have come out recently that feature Spider-Man 2099, and any X-Men and Spider-Man games based on their respective movie franchises)

There are, naturally, exceptions to the rules, some novels are considered cannon. I think there's a case where one video game is considered cannon as well.

I suppose the best policy would be that if a certain reality is depicted in a medium other than what it originated from we should assume it is a TRN until there is an official position otherwise.

In many ways this is a similar dilemma that both Memory Alpha and Wookiepedia have to deal with as well to varying degrees, I suppose we could look mirror these problems in the same way.
