Note that I didn't check whether this actually (and always) works: The
problematic obsolete variable declaration is performed in the function
`eieio-defclass-autoload'.  If the value of
`eieio-backward-compatibility' is checked when loading autoload
definitions, will a file local binding in the source library be
considered at all?

Oh, and let me add another important aspect: why does using an obsolete
name as the name of a _lexical_ variable trigger the "variable is
obsolete" warning at all?  If that would not be the case (and I don't
think it is useful) then in source files using lexical binding mode we
would not see the problem.
