It’s a little bit like asking for everything to be included in the Standard Library. Sure, it sounds nice at first, but now you need to maintain tons of dependencies. And any time you want to do one thing, you bring along the baggage of every other thing.

Languages are similar. They also change over time. So now if you want to release a v2 you need an updated corpus for all languages. Or if you get access to an updated corpus for a small language, it might not merit a new model version since it’s only one out of the 14.
