GL-X3000 Firmware 4.7.1 MWAN3 Policy Routing

Upon upgrading to firmware 4.7.1 it appears there has been a change from mwan3 to an internal kmwan module for performing multi-wan. I was previously using the luci-app-mwan3 package to manage policy based routing but it appears to no longer be functional with this new firmware.

My setup is Starlink as primary via ethernet interface with cellular as failover backup. However, due to Starlink's pricing model, I would use the policy routing to force media devices to stream via cellular.

How do I get this functionality working with this newer firmware?

2nd this one, I updated firmware and found that mwan3 is missing. I also use this for cellular / starlink host based routing.

It seems maybe the only fix is to downgrade the firmware back to the 4.4.x release?
