Based on your commits to github are you not planning on supporting AiMesh on Merlin Firmware? Or have you just temporarily disabled it whilst getting the new GPL working?
I don't have a final answer yet, but initial tests are hinting that supporting it properly might not be possible. While merging the GPL code I already spotted a couple of problems that might prevent AiMesh from working on Asuswrt-Merlin. Inter node communications is entirely closed source, including the trigger for new firmware checks and uploads. The new firmware check procedure for instance didn't work at all, possibly because the procedure is hardcoded inside the closed source AiMesh service, so it was contacting Asus's servers instead of mine.
For now my focus is just on getting all models to run on 384_10007. After that I will take a closer look at AiMesh, but at a first look, the chances of Asuswrt-Merlin supporting AiMesh are very slim.
