When merge?

I do also strongly support this pull request - I was just in the process of creating a similar one (see https://github.com/d3k4y/core)

I have a few questions though:
T9n.setLanguage('en'); import { en } from 'meteor-accounts-t9n/build/en'; T9n.map("en", en);

• Is it really necessary to set language and map?
• Is it possible to cleanly overwrite the language setting and map from within the depending application?
