What is the development status and plans on Named Tensors? I don't see any news or progress on it for the last six months at least. I want to use this feature for a system I'm building and am considering whether to build on top of Alex Rush' lib (http://nlp.seas.harvard.edu/NamedTensor) or extending the native but experimental feature. I would certainly prefer the latter but its codebase is C and I'm unsure of how robust or supported it is / will become.
