In order to avoid deployment of code that deterministically fails fatally in 2022, I'd propose to stop the doublings at 32MB for now and fix the message size limit in the mean time. Since the message size fix requires a 2nd hard fork anyway, your current 8GB limit could be re-instateted in that 2nd fork as well. Even if you disagree, I'd suggest to address the topic in the BIP. best regards, Martin
