that makes sense, but I wonder if this breaks --dev mode for op

reth/crates/chainspec/src/spec.rs

Lines 108 to 115 in 0746479

re-request review @mattsse

[mattsse]

cool, incremental progress.

one q re CI change, otherwise lgtm

[mattsse]

why do we need to change this?

[emhane]

because of the parse_dev test

[mattsse]

could we remove that, not worth changing the ci for and adding a single expectation in ci

[emhane]

then I have to remove the whole test
