What I'm asking is rahter: is it worth to worry about this?

Well, I wasn't thinking about a silent conversion for the uncertain
options: in the case of dubious options which we can guess (a vs A, r
vs R), a warning would be given, and for the unguessable case we could
either still give a warning and continue or even abort the process
altogether. Better than the silent conversion (which would not break
anything that isn't broken already anyway), although probably not as
sophisticated as your proposal.
