Maybe a big Thank You is in order, but from my end, from my website logs, this has been "thrust upon me". With my logs filling up with "/.well-known/acme-challenge/STUFF" requests that are totally irrelevant to me. (My website is static, with no need for such "security".)
Along with .env and other "stuff to help" things like this just add useless traffic. The problem may be that the Internet gets slower and slower as time goes by as well meaning programmers keep coming up with these kinds of things that help themselves more than little people with little websites.
There is no way to opt out, is there?
