Description

Currently, libwaku's GET_PEER_IDS_BY_PROTOCOL returns the peer ids of peers that have an open libp2p stream associated with a given protocol.

However, what's most interesting for us is the capabilities of our connected peers and not which protocols are we actually using.

For example, for req-res protocols such as Store, most of the time we don't have an open stream associated with the Store protocol - which means that with the current approach GET_PEER_IDS_BY_PROTOCOL won't return anything.

Therefore, changing the approach so we return all our connected peers that support a given protocol, even if we don't have open streams for that protocol in specific.
