It probably doesn't make much of a difference because Magit's stashing commands offer more flexibility that even after this addition is still missing from `git stash`. Stash creation is actually one of the very few areas where Magit doesn't use the respective Git procelain commands at all (as opposed to using them and then doing additional things using other pluming and/or porcelain commands as is the case in many other areas).
Also I have to continue supporting older Git releases anyway; people like to use the latest Magit version without considering doing the same for Git, for some reason.

Change the license to GPLv2 OR later.
