Sure, but do we actually care about that?
If we actually do care, we could throw a script in the build to make sure
anything in the linker script map is not used internally.
Right now, all this DSO hygiene and look up protection is opt-in, which
usually always results in missed cases. With the linker script, it's opt-out,
which is usually always how you want to do things.
