Yeah it was a conscious decision, but it's certainly not the only "one right way". I saw when Keras had an API freeze a few years ago, and thought that it didn't really make sense to me when the field is changing so much. I can certainly see that there will be people for whom that is what they want, however.

But v2 is designed to leverage a lot of the new ideas that have come up in the last couple of years, both in our research, and more widely.
