Simon McVittie and I once agreed on a suitable implementation for this, 
see https://gitlab.freedesktop.org/dbus/dbus/-/merge_requests/250. It 
would be helpful if you would create a corresponding feature request 
https://gitlab.freedesktop.org/dbus/dbus/-/issues/new?issue%5Bmilestone_id%5D= 
for this.
