This was a minor concern to me as well and I did try (for sanity's sake) persisting the binary objects while upgrading my app to newer versions of the protobuf library and reading the persisted objects worked like a charm. Like Marc mentions, the underlying binary spec has to be the same if it is to work across multiple platforms.
