The current implementation explicitly removes properties not declared by
the Platform module _before_ creating the Platform instance. So .. it
will work.
However, others might argue that we should be generating an error for
these properties rather than silently "fixing" the object. Suppose, for
example, that you simply misspell a platform's instance creation
parameter. Without an error message, you will be pulling your hair out
trying to understand why the platform is not doing what you want.
If it weren't for backward compatibility, I'd fix the current
implementation to generate an error. In a future release when we have
some flexibility w.r.t. compatibility, we might implement this fix.
