Random thought, but it really annoys me how closely associated to Bitcoin's success Lightning has come to be seen, so much so that it's almost like Bitcoin can't fully stand on its own as a technological tool without Lightning "enhancing" it. When you really think about it, Bitcoin and Lightning have nothing to do with each other at a protocol level; the Bitcoin network "knows" as much about Lightning as the Litecoin/Ethereum network does, i.e. nothing. The way Bitcoin and Lightning get thought about in a way where they're paired up and so closely linked doesn't feel right. Nowadays a lot of the excitement about Bitcoin is funneled through Lightning, that seems to be where all the buzz is. Even technical improvements to the Bitcoin protocol are viewed through the lens of "how will this help Lightning?" (Neutrino, eltoo, Segwit was heavily associated with LN due to the malleability fix, SIGHASH_NOINPUT: https://github.com/bitcoin/bips/blob/master/bip-0118.mediawiki, etc).

I hope we know that Lightning is quite blockchain agnostic and I'm sure they can pivot to another cryptocurrency or launch their own if the Bitcoin network doesn't suit their needs due to rising fees or disagreements with Core developers (I've already seen some areas where the difference in focus and priorities has reared its ugly head). Lightning is also particularly not suited to give a good user experience with higher fees: https://www.reddit.com/r/Bitcoin/comments/b9ec4v/lightning_channel_losing_funds_for_no_reason/.

I think there will be quite some drama if it looks like eltoo and SIGHASH_NOINPUT will end up live on the Bitcoin network. Neutrino is already well on its way to becoming a feature in Bitcoin Core: https://github.com/bitcoin/bitcoin/pull/12254. It's strange to have protocol development steered in a way to help one particular application. Not to say that all protocol improvements only help Lightning, but a significant chunk of work and effort recently seems to be pointed at the direction of bending and twisting the Bitcoin protocol so that it works better with one specific implementation of an offchain system. At least that's been my observation.
