IDL42 — The text in the "Scope" section provides history rather than scope

The content "Scope" section appears to have been copied from the original RFC motivation. As a result it reads more as a "history" of the specification rather than defining the scope.

The history of how the specification came about is useful and should be stated somewhere. However the main focus of the scope section would be to define the boundaries and goals for the specification.

Rewrite Scope and move historical background text to section 6

Most of the current text in Section 1 "Scope" is about the history of the specification. This text should be moved to section 6 "Additional Information"

A paragraph describing the goals and boundaries for the IDL specification should be written and placed in section 1. "Scope"
