I can with some amount of efforts - I'd need to read the code. If you
would be kind / enthusiastic enough to try this with Tizen images, that
would be a lot easier for me.
But let me CC Samuel who did tethering support for connman. Samuel, if

Yes, 100% sure. I spent a lot of time bisecting this, and found out that
in my setup tethering starts working only if I revert both.
