I didn't vote, but to answer your question, you couldn't possibly have done the "exact same thing" as a linux-specific userland exec technique and have it work as a DLL injection technique on Windows. I'm sure it could've been conceptually similar, but not identical, and maybe those differences would be interesting to discuss.
"Exact same thing" as in re-implemented a basic OS feature in user mode to bypass an intercepted feature. Obviously it can't be literally exactly the same thing, because that wouldn't be implementing something, but rather using existing source code.
