When importing a template like this:

zabbix_export:
  version: '5.4'
  date: '2021-09-02T06:34:30Z'
  groups:
    -
      uuid: 9becbe655a1448489e2539ed9f60686e
      name: Templates
  templates:
    -
      uuid: 0990793d930d46aa905fbba7ce3d0be7
      template: 'TemplateWithSecretMacro'
      name: 'TemplateWithSecretMacro'
      groups:
        -
          name: Templates
      macros:
        -
          macro: '{$SECRET}'
          type: SECRET_TEXT

The {$SECRET} macro is overwritten (made blank), even though no value is provided (the key is absent). This makes it more difficult to manage templates as code, as we need to make sure the secret is provided in template when exporting it, while making sure the secret does not end up in the repository.

Would it be possible to note overwrite the macro value when the 'value' key is absent in the macro?
