For large staking pools that already control thousands of validators, exiting and re-entering would be extremely slow and costly. The adoption of the EIP will be much higher by allowing in-protocol consolidation.

For validators that choose to raise their effective balance ceiling, allowing for custom partial withdrawals triggered from the execution layer increases the flexibility of the staking configurations. Validators can choose when and how much they withdraw but will have to pay gas for the EL transaction.
