IBM Toolkit - development of REST API Applications -- provide support for binary/blob data handling

Today, we see as lot of REST application handling binary data. A simple example is the upload of a file. 
See the OpenAPI extract below.

Unfortunately the IBM Toolkit is only able to handle JSON data formats for the REST API. 
This means e.g. when generating a REST API application based on a OpenAPI spec - the definition of binary data is 'just ignored'.
The same is true when updating an existing REST API project with a new/modified OpenAPI spec.

This is quite annoying as all required code changes within ACE need to be done 'manually'. 
Having an 'automatic support' for such binary data would make development much more easier and efficient.  

=== sample OpenAPI spec with a simple file upload
