Ah yes apologies, that'll teach me to look at the code before the readme!

Total tangent - I've often been annoyed at some library or whatever because I didn't like the way it was implemented or the api it exposed or whatever. So I try to reimplement it myself to my tastes, and eventually once I understand the problem and iterate a few times I end up with something remarkably similar to the library I initially didn't like.

It's a good reason to at least try to implement your own sometimes, rather than just use libraries - even if you end up just using the supported external dep, you'll understand it a lot better.

(not saying that's the case here, just that you reminded me of that with your convergance...)
