If there's no way the miners in the pool gets compensation for this, miner will leave that pool making such blocks less likely to happen.
If they do get paid for it, in a transparent way, more miners will join such pools and it will be a form of income.
Not sure where it goes from there. It might boost Lightning which isn't a bad thing. It might polute the mempool for years which isn't great.
Personally I think this will blow over and the mempool will be empty again.
