[RFC] Translatable HTTP response payloads

[ro0NL]

Description

In a controller it would be nice for i18n if we're able to do:

action() {
   return $this->json(['message' => new t('id')]);
}

The payload would contain the translated string, eg. {"message": "translated"}.

Note if one wants a custom payload, eg. {"message": {"id": ..., "domain": ...}} i tend to prefer a custom normalizer instead, or control it by a context option.

Example

No response

invoking translator service is relatively easy also 👍
