OK, but that's immediately before the bit that says:

   When this happens, one solution is to designate a "well-known
   location" for data or services related to the origin overall, so that
   it can be easily located.

"One solution" implies to me that .well-known is not aimed at cases where
there are other solutions, as is the case for CT. (Even if BCP 190 doesn't
like CT's solution...)

I can't find any discussion about which non-web protocols were the
inspiration for that paragraph, and what ways they were considered
problematic. Is there more to the problem than how to get from a host
name to a URL without trampling on the host's URL namespace?

Tony.
