Sounds like we are largely in agreement. Let's start on this after the Trac migration is finished.
I can in fact start working on this already while the migration is pipelined. It's just markdown in git, so writing a draft and then merging it into the wiki is perfectly straightforward.
I was going to recommend we rather just use something off-the-shelf to avoid reinventing the wheel. I use linkchecker [1] elsewhere and it works quite well. I believe you can use its -W flag to catch non-existent wiki pages (which won't return a 404).
Ofc, if we can do it without any extra coding effort, all the better. I do think doing it as part of the migration script might make it easier to capture those "redirect" pages (e.g. https://ghc.haskell.org/trac/ghc/wiki/Newcomers): we're scraping anyway, so I think detecting the shape of those pages shouldn't be overly difficult, and might be something an off-the-shelf link checker isn't as suitable for.
