It's list policy to reply-to-all, for just this reason.

Libvirt does not (yet) allow remote connections to qemu://host/session.
 You'd first have to figure out how to patch libvirt to allow remote
session connections; part of the problem is that with qemu:///system,
there is a daemon running that is always listening for remote
connections, but with qemu:///session, since libvirtd is only
auto-started as needed, there is no easy way to guarantee that the
remote machine is running a libvirtd process as the correct user.

No, virsh does NOT support remote session connections, at least not
intentionally.  If it works for you, it is a pure accident.
