What is the purpose of having map[peer.ID] => PrivateKey in PeerStore?

I am reading Go PeerStore implementation.

PrivKey - returns the private key of a peer.

What is the purpose of this? Is it possible that peer can know private keys of other peers?

We only ever use this to store our own private key, and fetch it from other parts of the stack, rather than passing it around standalone. Some examples:

Pubsub:

Identify protocol:

Swarm dialer:

It may be worth documenting the method on the interface to point this out so other users don’t get confused.
