Alternative required properties syntax

[alexeyr-ci]

I noticed in the examples required properties being specified as

      parameter name: :blog, in: :body, schema: {
        type: :object,
        properties: {
          title: { type: :string },
          content: { type: :string }
        },
        required: [ 'title', 'content' ]
      }

title: { type: :string, required: true }, seems more intuitive to me, at least. I see that the current style aligns with OpenAPI, but could both be allowed (and generate the same Swagger file, of course)?
