The problem comes down to how you use your model, which is all that matters. If there is a mismatch between the language in which your model is embedded in and the language in which your main application/interface is written in, then ideally you want a way to extract the model statically from the dev environment. It's not about type-checking per se, which is nice, but how you get the model out without having to, say, start a python interpreter in your server process just to do the inference (which is why in some aspect Tensorflow is more convenient).
