One option might be a positive incentive for LN mainnet txs that apply a further fee discount for well formed, distinguishable LN channel opens and closes. The incentive model has always been about lower fees for newer, more efficient tx formats, it can be encouraged to create more channels if the txs did not have to compete with non-protocol json spam.

Right now I am not opening or closing new channels, and am highly concerned about loss of funds for something out of my control. This high fee period has shocked me to the core re lighting security and fund safety, and I have lost 100ks of sats so far. I have my doubts about this particular L2 implementation if the macro L1 conditions make it highly unsafe for business.
