As part of the scenario described by @kevin-montrose in #34344, we'd like for the sockets transport to create a connection context from an already accepted socket. In Kevin's example, the socket is accepted in another process before being marshalled over an IPC mechanism.

namespace Microsoft.AspNetCore.Server.Kestrel.Transport.Sockets
{
    public class SocketTransportFactory
    {
       public static ConnectionContext CreateConnectionContextFromSocket(Socket socket, SocketTransportOptions options);
    }
}

The consumer of this API will implement a custom IConnectionListenerFactory and will call this new static method in their IConnectionListener.AcceptAsync implementation
