I think this discussion was sparked because I Community Wiki'd this question. As I mentioned in the comment I left upon doing that:
I've made this post a Community Wiki because it is a 'list of X' type of question that contains enough value to avoid deletion. That being said, these types of questions are some times maintained on Meta, rather than the main site — see an example on Japanese Language.
If you've read through the Help Center, at some point you'll have stumbled upon What types of questions should I avoid asking?, one of which are questions where:
every answer is equally valid: “What’s your favorite ______?”
That means that, for that question, I could either have closed it as off-topic because it does not adhere to the format our platform allows, or, since it had some value, I converted it to a Community Wiki (CW) with the intention that y'all do some clean-up on it and make maintaining that list a community effort. I even pointed to an example elsewhere on the network of how that's done, in case y'all needed some pointers, and further mentioned that some sites keep these on their Metas because they're generally considered off-topic for the main site but still have some value as FAQ-type questions.
Maybe I shoulda been clearer about the expectations around the question, so apologies for that.
As Grace Note wrote one this blog post about CW a while back:
Community wiki is for that rare gem of a post that needs true community collaboration. That’s when community wiki shines.
I recommend reading through the whole article, but essentially the quote above explains the general use-case for CWs: if you're gonna have an ever-growing list of answers, none of which is "more correct" than the other, AND the question is definitely on-topic, maybe it's a good candidate to CW.
