It would be interesting to see a country adopt a native stream cipher instead of a block cipher as their standard. The performance of stream ciphers is more competitive, you lose the requirement to define 8-10 "official modes" (most of which are insecure), and stream ciphers are virtually always what you want anyways: in 2015, block ciphers mostly exist in order to be transformed into stream ciphers via counter mode.
I'm not sure this is a major vulnerability in practice, but it is strange not even to mention 10+ years of cache-timing attacks against AES.
It's a weird question to ask, I think, because of the modern ciphers in wide use, the only non-AES cipher (heh) is an estream finalist.
