Not really. It just came up on #haskell, and the arbitrary limit has bothered me
before every time I've seen it.

Changing the function to only work for decimal digits would be another way to
get rid of the wart, but that might break existing code, unfortunately.
Since people seem to be against the proposal, I'll hereby withdraw it.
