I would like to be warned when a select setting's default value is not a valid option.

Describe the solution you'd like
Writing this setting in a block/section/settings_schema.json should warn me that the default doesn't match the options.

  "settings": [
    {
      "type": "select",
      "id": "alignment",
      "default": "this-is-not-an-option", 
      "options": [
        { "value": "flex-start", "label": "t:options.alignment.left" },
        { "value": "center", "label": "t:options.alignment.center" },
        { "value": "flex-end", "label": "t:options.alignment.right" }
      ],
    },

Similarly, I'd like the presets to warn me as well if a setting value in a preset is not a valid option.

  "presets": [
    {
      "name": "t:general.column",
      "category": "t:general.layout",
      "settings": {
        "layout_direction": "group--vertical",
        "alignment": "this-is-not-an-option",
      }
    },
