We propose to include EIP-3541 in London (it is only an EIP PR right now, but hopefully gets merged in a few days).
This change is very simple itself and is the first step of the larger EIP-3540, which we hope to have included in Shanghai.
It is important to consider 3541 for London, otherwise 3540 would be delayed to Cancun at earliest. We think including 3541 will not cause any delay to London, given its simplicity.
