Comment (by jryans):

 From talking more to dgoulet, we believe that the cases of private keys to
 remove are:

 * `signing_kp` in `hs_desc_plaintext_data_t`
 * `blinded_kp` in `hs_desc_plaintext_data_t`

 while on the other hand, the following are okay since they are known on
 the client side:

 * `curve25519` in `hs_desc_intro_point_t`
