Ok, yeah. It occurs to me that websites might want the whole path to be variable text, maybe user defined.
This would also answer the question I've had for so long as to why Wikipedia chose to have /wiki/ before article titles in their URLs. I guess it was so that the article https://en.wikipedia.org/wiki/robots.txt did not collide with their robots.txt file.
Would've been nice if that explanation were included in the RFC.
The RFC says:
> 2. Why /.well-known? It's short, descriptive, and according to search indices, not widely used.
This gives reasoning for the name of the subpath, but not its existence.
