Any plans for supporting multipart/related?

For openocr I used multipart/related (rfc2112) for uploading image data via a REST API, and was wondering if Swagger is currently able to support this and/or planning to support this?

Is there a more common way of uploading multiple binary raw data chunks via a REST API than multipart/related?

Seems like we need to expand support to multipart in general. Perhaps it'd be better to keep all suggestions under #303.
