It's "well known" if you've manually set up SSL certs for a site using certbot. But yea I agree it's a weird choice to put it there instead of the same place as humans.txt, robots.txt and etc.

I wasn't going to add one but I might actually put one in my root just out of spite.

Devs need to stop demanding other devs jump through pointless hoops.

On linux, there is a ~/.config directory, yet devs who think they know everything still pointlessly litter my home directory...

Don't litter you web root either ;)

Au contraire, it's the other way around. It makes more sense to put favicon.ico, robots.txt and humans.txt in .well-known, but that's life, these files are legacy. (shrugs)

Iirc “they” decided that all new standards for “specific URLs you may want to serve for a particular purpose” will be under /.well-known. Robots is grandfathered because it’s super old and established and thus crazy to move. There won’t be anymore “at the root” standards.

I do get why they standardized it that way, but boy is it ugly.
