The only translation that is going to be bundled with OctoPrint for now will be .de, if at all. The reason simply being that this is the only translation I can update myself and hence guarantee a good user experience for.
setup.py now offers two new commands, babel_bundle and babel_pack, with which translations for plugins and core OctoPrint can be automatically bundled or packed as language packs once compiled. This should make sharing translations quite easy in the future.
