I don't see this as a modern vs old API style, it's consistency.
`Arrays.copyOfRange()` is from 1.6. I think it's being consistent with other
JCA classes, like Cipher, Signature, MessageDigest, and Mac. I'm not aware of
any JCA that uses (from, to).
Also `Arrays` methods use length of any size. KEM does not. In fact it is
very obvious what the length is as it must be the key size when looking at
`DHKEM.decapsulate(...)`:
Objects.checkFromToIndex(from, to, params.Nsecret);
One could argue that `to` isn't necessary given the length is fixed by the
`params`.
