Literally no one asked you to dox yourself, you said you were a developer so I said show me some stuff you developed and then you said no that will dox me, completely disingenuous but you haven't been very honest thus far anyway.
Yes the term L2 is used as shorthand to describe Liquid but it is in fact NOT an L2, it is a sidechain. To be a direct L2 on top of bitcoin you have to be able to have unilateral exit to the base bitcoin chain, an example being an HLTC.
Out of band payments are essentially no different then payments in LN channels which themselves are just unpublished bitcoin transactions and thus present little to no risk. It's a feature not a problem and can reduce congestion and lower on-chain transaction costs. Everything can always unroll to the chain if necessary so there should be no lost transparency or trustlessnes.
Plus CTV can do so so much more than just increase efficiency and create better vaults.
Have you even read/studied the CTV use-cases on utxos.org/uses ?
You still seem to be grossly misinformed as your primary source of information seems to come from podcasts instead of any actual research and development.
I'd say I look forward to your reply but it will probably just parrot more podcast quotes.
