Comment:

 The public key is really not useful to tor right now.

 The reason we have tor write it to disk is because of the not implemented
 offline key feature where tor will need the public key to generate the
 .onion but won't load any private key. Instead, it will load a series of
 blinded key pre-generated by the operator.

 That being said, we don't have this feature anyway but we still put the
 public key on disk so if we get the offline keys let say next version, an
 operator would be able to remove the private key and tor would work out
 with the public key.

 But true, tor should write the public key on disk if only the private key
 is found.
