BTC being stress tested with millions of on-chain transactions could be great news for bigger block Bitcoins.
If BTC with small blocks cannot operate efficiently as a large payment network the small block narrative collapses

Lightning Network withdrawals to the Bitcoin main chain generally cannot be batched. While the Lightning Network itself allows for the batching of multiple transactions within off-chain payment channels to improve efficiency, the process of moving funds back to the on-chain Bitcoin network (often called "looping out" or using a "swap-out") typically treats each withdrawal as a distinct on-chain transaction.
Platform Limitations: Specific platforms like Bitget explicitly state that "The Lightning Network does not support batch withdrawals," requiring each transfer to be processed individually.
Technical Mechanism: Converting off-chain Lightning funds to on-chain BTC usually involves a "reverse submarine swap" or a direct channel closure, both of which result in a single on-chain transaction per batch of funds rather than a consolidated batch of multiple distinct withdrawals.
Exceptions via Services: Some third-party services (e.g., Bitcoin Well) may offer a "batched" transaction option where multiple swap requests are consolidated into one on-chain transaction, but this is a service-level feature rather than a native Lightning Network capability for standard withdrawals.
Unlike standard Lightning transactions which are ephemeral and never recorded on-chain, every withdrawal to the main chain requires a confirmed on-chain transaction, meaning the batching benefits of Lightning do not directly apply to the final settlement step unless facilitated by specific custodial or swap services.
