I think you're asking whether there is (or should be) a procedure or
guidelines for choosing a short name. There is none.

My point is just that there is far more "name space" available in two-
or three-letter "shortish" long option names than in single-letter
option names, so we are less concerned about "using them up".

Not sure exactly what you mean by "we extend that". Yes, we can just
choose something like "--ie" now. If, in the near or far future, we add
a new option such as "--ignore-existing" and want a shortish alias for
it, then we can't choose "--ie" but we will have plenty of "room" to
choose another reasonable abbreviation for the new option, such as
"--ix" or "--iexist".

So, for now, I would suggest "--ie".
