I think this proposal is relatively straightforward and clear, thank you for setting it up @Ben. I think this preserves the idea of having a BB&B mechanism in Botto without being prone to frontrunning. The reduction in weekly buy pressure might be slightly noticeable, although I suspect with the majority of other changes, this reduction will become negligible in the coming few months. Regarding the quantity burned, I would align more closely with 100% of BOTTO equivalent being burned rather than any other %. This is for simplicity's sake and the difference would be negligible until proven otherwise.
I understand that you, among many of us already have an idea of what to do with the extra treasury ETH, I would propose we hold off on further suggestions until after the treasury summary is published (+-2 weeks from now). I distinctly remember you might have posted some calculations re. PoL on #governance-discussion and timeframe to achieving fully PoL. Perhaps you could share that publicly (even if it's napkin maths, it helps!)
Returning to this proposal, there are no development implications here besides probably touching up our Discord bot (monitoring the sender address -> 0xdead, from memory we're burning directly from the SR botto.eth address, not the multisig). I'll double check that for us.
I would encourage anybody who might not fully understand certain concepts to ask them here!
