You mean things like adiantum? We could add a flag for that so
the skcipher wrapper linearises the input before calling lskcipher.

Is there any practical difference? You could always represent
one as the other, no?
The only case where it would matter is if an algorithm had both
an IV as well as additional state that should not be passed along
as part of the IV, do you have anything in mind?
