Standardizing on Oxford English

Hello,

I noticed the Documentation/SubmittingPatches file reads:

We prefer to gradually reconcile the inconsistencies in favor of US English

May I ask why? US English is highly idiosyncratic, illogical, and used
by a minority of the English-speaking population of the world (see
https://en.wikipedia.org/wiki/American_and_British_English_spelling_differences).
Since British English has its own idiosyncrasies, why not use Oxford
English, the most international English that is used by millions of
the world? It is used by practically every international organization
(such as the UN, ISO, IEC, BIPM, NATO, etc.), taught in practically
every school in non-native-English-speaking countries (and even
native-English-speaking ones), and used by myriad publications (e.g.,
Nature) and people around the world. Given the inherently
international nature of the Git project, it makes complete sense to
follow suit.
