BinaryLoader created from IMultiStreamSource not Stream #2052
Description
Whenever a binary loader is created, it can be crated from either a path or a stream. It is inappropriate for the public API to intimate that it is possible for the binary loader to be creatable from a stream. Even though it can be, this is a historical accident as the format (and its reader) predates IMultiStreamSource. Rather it, like all readers of this shape, should take IMultiStreamSource. That internally it operates over a single stream is an implementation detail that should not be visible externally.
