Since Leica no longer makes a Viso, that argument is out. And I cannot perceive using an M camera with long lenses and flash. I mentioned the flash metering from the actual framed subject but as you say, this can be a disadvantage for off center subjects. basically, I believe, as I think you do, there is little use for "just" the addition of TTL flash on an M camera without finishing the job.
