we never intended that the ssl ciphersuite addressed cert algs.
one has to be carefuy in designing security protocols (specially if one knows something about how they can and typically are designed-in by standards committee “consensus” to be broken by cryptanalytical hardware tuned into oracles).

That gave me the hint I needed. I ended up with:
I'll add +AES-256-CCM once I know it is happy on my box.

Sounds like a plan.
