Even if they are still worthwhile, I'd just put them in the core code rather
than having the additional module. Too trivial for it to make sense
in a utility module.
I'm inclined to agree with Lars that the recent changes reduce the argument for
having these to marginal at best. Bad luck for crossing with those!
