The block height validation is gated by the startup option `con_blockheightinheader`, accesible in custom chains only using option `chain=<name>`. Only if set to true will this field be (de)serialized and evaluated in consensus logic. Otherwise the field is simply ignored, other than being stored in memory as the default value 0.
