you will need to refer to a blob commit of the relevant content rather than a PR (once PR is merged i guess)

@dapplion we are modifying the regex to support the compare diffs in drafts instead of PRs as the diffs are static: so basically this for your PR: https://github.com/ethereum/consensus-specs/compare/1c35eb1c3303fe1e0b101323106d766d8f848cd6~3...1c35eb1c3303fe1e0b101323106d766d8f848cd6 which is this link

I suspect this EIP is trying to address a common problem faced by staking pool operators: How can their customers be sure that the operator won't keep the created validators active forever (this allows the operator to profit from transaction fees and MEV)?

To solve this problem in a more comprehensive way, it may be beneficial to also introduce a new type of exit message that identifies the exited validator by their public key. This is an improvement because it will allow the staking pool to share the signed exit message with the staker before the staker has committed to fund the created validator. This is not easy to do otherwise, because the final validator index is now known until the deposit has been processed by the beacon chain.

I've written more about this here:
ethereum/consensus-specs#2666

One possible work-around with significant downsides is to require the operator to sign a very wide range of exit messages that target all possible validator indices.

some clean-ups in language and links to get this thing mergeddd

Specification changes are built into the Consensus Specs Deneb upgrade.

The specific makes one change to the state transition function:

• Modify process_voluntary_exit](https://github.com/ethereum/consensus-specs/blob/75971a8c218b1d76d605dd8b88a08d39c42de221/specs/deneb/beacon-chain.md#modified-process_voluntary_exit) to compute the signing domain and root fixed on CAPELLA_FORK_VERSION.

Additionally, the voluntary_exit gossip conditions are implicitly modified to support this change.
