Adding topics for discussion:

From @nflaig:

• we need to implement at minimum "lazy" slashing behavior in the beacon node: Lazy slasher OffchainLabs/prysm#15066 and https://ethresear.ch/t/a-lazy-approach-to-slashers/22041
• proposer boost reorg MUST be enabled by default, see ⁠proposer boost reorg: fix: proposer boost reorg #7428
• our attestation packing needs to be more thoroughly reviewed, also aggregate packing / misses. I already found a bug fix: update pruning to account for increase of max attestation inclusion slot post-deneb #7636, see: https://discord.com/channels/593655374469660673/1354566688724619274
• we need to enable IDONTWANT, since we ignore this message right now, it seems hostile behavior to network health since we add download bandwidth to other nodes by sending them useless data, see ⁠libp2p 2.0: https://discord.com/channels/593655374469660673/1349414588667400333
• we need to implement backfill sync and serve blocks up to MIN_EPOCHS_FOR_BLOCK_REQUESTS (and blobs) after checkpoint syncing the node to last finalized:
• there is probably more, but need to more thoroughly review specs / code

• Add temperature check on ePBS

For proposer boost, I suspect that there is preference to wait until after mainnet electra before continuing on this as it's a higher-risk merge and we want to avoid that before Pectra mainnet.

Including some questions/feedback from EPF if anyone has any. Please see questions in Discord.
