I currently do not see any reason why we should support so many different versions of AES-GCM and AES-128 by default. The defaults should provide high security as well as decent compatibility to solutions from other vendors. I am currently not sure whether ChaCha20-Poly1305 should remain as default as AES should usually outperform it by far. We can assume that most hardware has support for AES-NI.
