The reason is because it's supposed to be a standard folder that isn't in use accidentally for other purposes. It's exceedingly unlikely that a website is going to just happen to make content available in a hidden directory path without it being created by automated tooling (which would likely be aware of such standards). The entire point is to avoid adopting a path that people already publicly use for something else. A hidden directory is the best way to do that.
