Thank you, that is very helpful.

I am having trouble articulating the sense of unease I am feeling
over this issue...

The best I can muster right now is this: Reading section 2.3 of BCP190
I see nothing whatsoever that speaks to the interoperability concerns
that motivate the normative language in that (or for that matter any
other) section of BCP190.

In other words: what parts of the web will crash and burn as the result
of CT having an API that specifies a uri structure outside .well-known?

I'm sure there is a perfectly reasonable answer to that question. Maybe
this understanding is what the CT WG needs in order to get past this
issue??
