What I meant to say is that we currently call `ObjLayout::initialize()` after `Arguments::parse()` and `Arguments::apply_ergo()`, pretty much like what we do to initialize OS subsystem. I think that's the point where object layout-related arguments are definitely set. There is `Arguments::adjust_after_os()`, but I don't think it can reasonably change obj layout flags without breaking the rest of the setup.
