I am confused about both the purpose of .well-known
exceptions and so many conditions. Is this just something temporarily put in place by the host or is it best practice to keep it in place? Why are there two sets of conditions and rules. Can they be combined into one set?

.well-known
exceptions are for, or are you asking what the purpose of the rule is?
