Excellent, just one comment overall.

Test is going to pass but the test is only going to test empty account calls because there's no precompile here prior to Prague.

We should test whether precompile_address is in fork.precompiles(), and if not just pytest.skip("Precompile not enabled") at the start of the function.

LGTM, thanks for these :)

I checked the coverage lost and it makes sense: We are no longer calling empty accounts (the disabled precompiles in prior forks).
