When will OP stack chains support EIP-7702?

It took Perplexity Pro and 17 steps in "Research" mode to answer this question, so sharing these notes in case anyone else was wondering.

Nice! And just to understand (without having checked the sources), the summary is legit?

@timdaub.eth Yes, it was able to suss out the correct activation date for OP stack (but failed to provide meaningful results for Arbitrum and Polygon).
