I don't think so. Both are statements of truth.

If I had had time, I would have got this update mechanism sorted out
months ago. The fact that I didn't have time is not me saying that "I
don't want other people to have input into this process".

It's true that people saying "Please don't do anything like that" are
unlikely to be heeded. But that was just as true months ago as it is now.

Yep. In six to eight weeks, usually.

I've added to my ToDo list an item to check that list against ours.
Although again I stress that just adding ".zz" to the list is the same
as having no entries, because it's just an explicit encoding of the
default behaviour.

I didn't say anything about significance. It was merely a factual
statement about the number of websites. I don't have the ability to
determine how many sites there are in .je (I'm sure many people reading
this list do) but I'd wager it's four orders of magnitude less than the
number in .com, and at least two less than in .co.uk. And so ad-serving
companies are unlikely to be optimising their tracking systems to track
visitors across different sites in .com.je (even if that exists; I don't
know that it does). Perhaps I should continue to use ".xx" or ".zz" as
an example?

I very much doubt that established businesses will change their domain
name just so they can track users more accurately. ("Welcome to
cnn.xx!") I think you overestimate the impact of this change.

Done; thank you.

To be entirely honest, I was under the impression that this was still
the case. I am looking into the question.

There's always more work to do :-)
