Couldn't the dark bytes just be shipped as a separate file - for those who need it?

Is it clear that the “dark bytes” are “useless” debug information? It sounds like it’s just stuff not in the symbol table.

I did keep waiting for some point in the blog post where they would null out the "dark bytes" and see if/how the binary runs.

It won't. If you try to remove this information your program will crash as soon as the GC runs or someone calls systemstack, i.e. pretty much instantly.
