[mattsse]

Describe the feature

this type doesn't make much sense

reth/crates/chainspec/src/spec.rs

Lines 1105 to 1113 in a8cc335

	/// A helper type for compatibility with geth's config
	#[derive(Debug, Clone, Deserialize, Serialize)]
	#[serde(untagged)]
	pub enum AllGenesisFormats {
	/// The reth genesis format
	Reth(ChainSpec),
	/// The geth genesis format
	Geth(Genesis),
	}

and should be removed, the only supported input should be Genesis
