Re: [bitcoin-dev] [Mempool spam] Should we as developers reject non-standard Taproot transactions from full nodes?

I think one of the bigger problems facing the broader Bitcoin ecosystem is the lack of Lightning wallets for desktop. Mobile wallets are not really an issue, but as far as I know for desktop builds, there's really only Electrum, and Zap Wallet which support Lightning.

The alternative is interacting with the LN node directly, which probably won't be so bad, but it would be better if they carried GUI wallets like BItcoin Core does. Because windows and buttons help with mass adoption of pretty much everything.

I may even consider developing a Lighting wallet given the circumstances.

If I want​ to close my Lightning channel during a protracted fee spike where I have to pay an onchain transaction fee greater than the amount I am receiving you want to stop me doing that? You are impinging on a valid use case as well as requiring a consensus rule change.

Due to side projects such as BRC-20 having such a high volume, real bitcoin transactions are being priced out and that is what is causing the massive congestion that has arguable not been seen since December 2017. I do not count the March 2021 congestion because that was only with 1-5sat/vbyte.

Considering that miners are largely the entities at fault for allowing the system to be abused like this, the harmony of Bitcoin transactions is being disrupted right now. Although this community has a strong history of not putting its fingers into pies unless absolutely necessary - an example being during the block size wars and Segwit - should similar action be taken now, in the form of i) BIPs and/or ii) commits into the Bitcoin Core codebase, to curtail the loophole in BIP 342 (which defines the validation rules for Taproot scripts) which has allowed these unintended consequences?

We indirectly allowed this to happen, which previously wasn't possible before. So we also have a responsibility to do something to ensure that this kind of congestion can never happen again using Taproot.
