While lightning network provides a much better solution by compressing the fees and times by a great scale and making BTC ready for mass adoption. But what until it doesn't hits the market? BTC dominance is already under 45% they need to launch it very soon to avoid further questions on the supreme command of bitcoin.
You missed the point that LN, now using a version of Tor based routing, will be UTTERLY inefficient. You are trying to shoehorn fast payment methods into a subsystem whose primary objective was to obfuscate the very connections that need to be optimised to keep fees and time reasonable.
Have a look at bolts 4-7 specs to see how hideously complex and unfit for purpose these layers have become.
When they finally realise that this is not going to work on any scale ( like Poons original, now binned proposal) it too will need to be binned. Welcome to your next 18 month delay.
Is there somewhere I can read up on this? And the rest of the stuff you mentioned? thanks
