Sorry if I was unclear earlier.

Here's below what I'd like to see in this PR

 - Reintroduce `ContentStream` as a property and decorate it with an `[Obsolete("This property will be removed in the next release. Please use one of the the GetContentStream() overloads instead.")]` attribute
 - Decorate the `Content` property with the same attribute
 - Rename the two current `ContentStream()` overloads to `GetContentStream()`
 - Obsolete `ContentAsText()` overloads by decorating them with an `[Obsolete("This method will be removed in the next release. Please use one of the the GetContentText() overloads instead.")]` attribute
 - Introduce GetContentText (with current `ContentAsText` API and behavior)

Here's below what I do not want to see in this PR

 - Introducing a new method (whether it is an extension method or not) which returns the content of a `Blob` as a `byte[]`
