I would like to propose EIP-4444, dependent upon shipping EIP-6110.
We are already seeing discussions/disagreements around how clients today are bounding historical state on disk and in sync. Codifying a behavior in an upgrade will help solo-stakers and node operators at a time when we need more client/hardware diversity, not less. Portal Network has also signaled their readiness to serve historical state data. The cherry on top is that its implementation within clients is optional!
If we can tie 6110 together with 4444, some of the EL/CL complexity goes away. 4444 would allow clients to remove code tied to historical block processing. With EOF, there may be more simplicity in overall maintenance of EVM client code. This change also plays nicely with the Verkle transition as it could allow for more room on disk at the time of the transition, but may need to be shipped in advance…
