Oh, of course :)

Well, the discussion here has flourished rather more than I expected
it would. He's not too fussed about the LaTeX side of things (broadly
speaking) and I'm sure he'd certainly be happy if inputenc was less of
a hassle for new users. I'll keep him informed via the XeTeX mailing
list of the result of the discussion here. (If it's fixed in LaTeX
proper, it's out of his, and my, hands; if we write our own inputenc
then he might have more to say about it.)
