> Another problem is that if you yaw slightly, the yawed backward wing gets more straight on airflow, and the forward wing gets less, causing a stronger yaw force

According to geometry, this problem must also occur with conventional backward swept wings.

The geometry makes forward swept wing destabilize further, while classic design self-stabilizes (or oscillates).

That said, slight forward swept had been used for years in many planes, it's the more extreme angles that get the fun mentions.
