I can see how it could lead to more overhead when communicating with the requesters. That could be a lot in the event that lots of them might want to crawl your resource. I can see the argument that if I want to hide something, I should put it behind the layer of authentication. Robots is not a substitution for proper access control mechanisms. It is more of a "if they do honor this document, this would reduce the unnecessary traffic to my site" notion. I appreciate you highlighting your personal experience in dealing with bots! I like the ideas of monitoring and being behind something like Cloudflare tools which would protect against the major influx of traffic. I think this is especially important for smaller sites which either use low or free tiers of cloud services.
