I'm sure there might be some other edge cases, we need a way to safely load these things automatically, perhaps we add a flag per block?

wp_register_script(
$editor_script_handle,
$script_url,

$script_asset['version'],
true

$settings['editor_script_handles'][] = $editor_script_handle;

Same as editorScript there also is a script property in block.json that loads in both places
