Hey, etherfi team here 
We support EIP-8205.
we currently use a protected multi-step validator onboarding flow: an initial deposit establishes the validator, followed by verification of the intended withdrawal credentials before we fund the remaining balance. This is necessary because the current first-deposit-wins model leaves protocols exposed to validator deposit front-running.
EIP-8205 gives Ethereum a clean native primitive for the property we need: binding a validator pubkey to its intended withdrawal credentials before funding. With an atomic proof of an active, unexpired preregistration at deposit time, it can reduce custom protection logic, avoid capital being tied up in pre-deposits and the entry queue, and make operator onboarding simpler and safer.
We believe this is the right problem to solve at the protocol layer and support its inclusion in Hegota
