Why not, indeed? Still, that would need a character sheet, which doesn't exist yet. There is not a real agreement on what kind of sheet is needed and the devs have not made a decision about it.
And it also depends what is "useful data" for you.
For me, the portrait is the most useful one, as it enables me to use the same tokens with very different characters and because, IMHO, portraits add a lot of character to the tokens (of course, you can always use portraits as tokens, but they are small and don't show the orientation). It is also, probably, the result of overexposure to Maptool.
Anyway, this is certainly the feature I am the most eagerly waiting for.
