Support text/plain Media Type in CloudEventJsonInputFormatter

I don't know that this could be considered as an issue or not, but I want to ask/suggest it anyway.

We are trying to use cloud events on OpenShift platform. Our problem is the system sends events to our ASP.NET Core application with text/plain Content-Type. We solved this by copying source code of CloudEventJsonInputFormatter to our project, changing its name to CloudEventTextInputFormatter, and changing SupportedMediaTypes to text/plain like this:

SupportedMediaTypes.Add(MediaTypeHeaderValue.Parse("text/plain"));

Since the underlying ReadCloudEventAsync method does not make any transformation while reading the request body, it works like a charm. Here is the code for assigning Data field.

cloudEvent.Data = await new StreamReader(httpRequest.Body, Encoding.UTF8).ReadToEndAsync();

What do you think? Could it be integrated into CloudEventJsonInputFormatter? All it needs is the SupportedMediaTypes line I shared above. I could be like this:

SupportedMediaTypes.Add(MediaTypeHeaderValue.Parse("application/json"));
SupportedMediaTypes.Add(MediaTypeHeaderValue.Parse("application/cloudevents+json"));
SupportedMediaTypes.Add(MediaTypeHeaderValue.Parse("text/plain"));

Start with CloudEventJsonInputFormatter and its SupportedMediaTypes configuration, then inspect how ReadCloudEventAsync handles the request body. Confirm whether text/plain should be accepted alongside the existing media types and identify the relevant formatter behavior to verify. Done means text/plain requests are supported without the copied formatter workaround.
