Isn't Postject concerned only about resources that are injected post-compilation?

[jviotti]

In theory, whether a resource is injected pre or post compilation doesn't even matter, as they both result in sections/segments appended to the binary. I believe this was raised by @dsanders11 as a way to test that the reading operation is done correctly and does not depend on quirks about how we actually inject with Postject as well.

I would say no. The run-time API is agnostic to how the resource was added, pre or post, and I think there are valid use cases for pre, it makes things simpler and is guaranteed bug free, since it's using standard techniques.
