In retrospect, it was obvious the letter they signed was justification to merge a clearly controversial PR. It's not obvious what the second and third order effects will be, but I guarantee this will not play out the way that the signers of the letter think it will.

Happy to eat my words and say that I was wrong if a year from now if there isn't a significant growth (>100%) in large OP_RETURN outputs (>160 bytes).

I challenge any signer of the letter to provide a similar metric to measure whether what they're doing works and under what conditions they'd be willing to admit they were wrong.
