I don't need to exclude it. I just wanted to avoid another layer
of pcrypt here because it does not make too much sense to parallelize
a second time. If the aead algorithm is already parallel it would just
add overhead if we parallelize an underlying algorithm too.
Anyway, I would not mind to allow more than one pcrypt layer.
