Is this rack setup safe?

This rack is setup with p clips at the bottom of the forks which I've been assured are quite strong however with some weight it wobbles slightly, more than other racks I've used in the past. Obviously I'll never be moving the handlebars like this when riding but given this setup is intended for some off-roading, does anyone with a more physics based mind/direct experience with this have any advice other than change the fork to one with stays. Thanks for any answers!
