I agree that cleaning up dinged or nicked threads is useful, and use both triangular and thread files for all sorts of work.
BUT
It's not appropriate for a stripped thread, since the issue is that the peaks are too low to engage the mating part. Filing away more material won't raise the peaks, and so is useless in this application.
