Not really relevant in this case (that the article talks about), but I don't think that it is so cut and dry as "someone spent time on this so we have to keep it".

No, and I'm not arguing for that. Just pointing out that that insidious nature makes contributing to Wikipedia a questionable activity for (a few|some|many|???) people.

To be clear, I'm not arguing for having NO standards at all for what's included, but I think there's room to rethink the nature of some of those standards.
