The feature is only useful for generation of keys with size bigger than PRF output. Arguably, PBKDF2 should not be used with such key sizes and users should instead use a separate KDF.
I suggest removing the parallel feature and add advise against using PBKDF2 with big output key sizes in the crate docs.
