Can Cancelled Works Have Their Own Pages?

I asked this in ATT a few days ago, but after 30+ replies it was noted that the discussion should be moved to the forums.

Can cancelled works have pages if they have enough tropes to not be a stub? "Cancelled" as in they've never been released, most likely will never be released, probably didn't finish development, and have never been leaked online in full (or had a script posted). We're not talking about Star Fox 2 or Thrill Kill, which have complete or near-complete builds circulating despite no official release.

Castlevania: Resurrection has a page despite being cancelled nearly twenty years ago. No build of the game has been released, afaik. Sly Cooper and The Governator also have pages despite both being cancelled years ago.

From what I know, it's against the rules to trope What Could Have Been examples. That means deleted scenes, Cut Songs, developmental elements, etc. But most cancelled works seem even less reliable than something like a deleted scene, which is usually released officially.

Huge bump because this thread came up in ATT. While the OP of this thread hasn't been active in 2-3 years, this discussion may be relevant to the topic of the ATT—that of what to do with Film.Dark Universe.

We have two whole indexes of cancelled works. I think the general consensus was that there should be enough of a work to trope it in some way.

For example, something like Justice League: Mortal is okay, because we have a full script to work off of. Even though it was never filmed, we know exactly how the story plays out and can list tropes accordingly. Meanwhile, something like the recently cancelled Batgirl movie had it's page cut because we had practically nothing on the film. No clips, no trailers, not even a script to work off of.

Like I said on the ATT thread. I think the Dark Universe page is fine. There's enough tropes there to meet the requirement, troping announced ideas and the promotional material.

I don't know, I think the sheer lack of material beyond the 2017 Mummy movie makes it not viable to have its own page. At least other cancelled projects have script drafts, concept art, sometimes even storyboards to make them tropeable.
