Other than wanting to have every desynth, there really isn't much point to alts beyond visuals and aesthetics (both of which I completely get - the latter one especially). There are enough grindy achievements (craft x of y-z level, gather 5000 in this level node) that I can't imagine wanting to repeat them. For the non grindy cheevos, you're likely right, there are people who enjoy part of the experience.

Still, I think account wide would be a net gain for most players.
