I can think of at least one scenario where you might not easily have
access to any invented ID - you're the author and you have mailing list
me-too turned off, so you don't have anything that the mailing list has
inserted. I honestly think we should just stick with the Message-ID
value and get over the ugliness.

Putting the clickable URL in a header("X-Archive-Link" ?) is a good
idea, though. Using my MUA (Thunderbird) that would make it as simple to
get as View Source (Ctrl-U) and a simple C&P, which would make
committers' lives easy. I bet others might appreciate it too.
