1/ I believe that the chain temporarily halting for 6-12 hours is a preferable option to penalizing over 80% of the stakers, especially until we attain a sufficient level of client diversity within Ethereum. We've learned over the years that downtimes don't kill chains.

But if the supermajority client (Geth) unexpectedly & suddenly finalizes an invalid chain, how does halting the chain afterward help? Sure, you avoid inactivity leaks for a while, but at restart, those Geth nodes can’t get back to the valid chain without being slashed, since they already attested to the invalid chain

We'd have to disable inactivity leak and rely on social consensus to revert to the correct chain. Of course, this should be strictly temporary (never for long term) until a set deadline, before which we hopefully achieved adequate client diversity. It's not ideal, but it's less terrifying than destroying 20M+ ETH.
