Thanks both, yes will add a doc comment also.  Currently the generated docs give you: "Deprecated, for removal: This API element is subject to removal in a future version." But will add more around that.

MLetObjectInputStream and MLetParser are not public classes, so thinking they are not part of the public API we need to deprecate before removal.

Happy to try and avoid test logs being full of excess noise with those suppression annotations... 8-)
