100% correct on all fronts. Good thing is the on chain 'leakage' is from Postmix coins. Not quite as easy to achieve these days unfortunately, but that was the impetus for my recent LN native buy/spend/save flow.
I'm monitoring your thread about default blinded paths apparently not being default. I too fell for the same assumption.
I thought CLN had full support for bolt12. Seems like it doesn’t support blinded routes for offers best I can tell. Strange considering a main contributor to the CLN implementation is the author of bolt12.
And I personally regret not mixing more while I had the opportunity. I assumed wrongly I’d always be able to mix in the future.
Delve into JM while fees are low!
