It's just different implementations/code paths. The dynamic format is
really one single format that can do many algos and combinations of
algos. It can do raw too, so lists them. Sometimes they differ in max.
length. Many years ago, dynamic would even do them faster in some builds
but nowadays (especially on Intel stuff) the dedicated formats are
usually faster.
Moreover, we now also have the "dynamic compiler" formats that are even
more generic (so even less optimized but OTOH very flexible).
