And if this project was one monolithic thing, I'd agree. But the page sells this xnu_override as a "reusable library" which might lead someone to try to reuse it in another place. This is scary and hence my warning. Hell, tomorrow's apple 10.13.0.0.0.0.0.0.minor.insignificant.0.1 patch could change these "invariants"
You're right, and I was reacting poorly to the "don't run this on anything" statement. It's some hacker magic off github, caveat empor. You're also right that future updates could break it. It's brittle. I won't be running it myself.
I bet, though, that 99% of the time, it works every time, and for its use case, that's "good enough." Hot patching the kernel is scary, though, and hopefully no one walks away from looking at that github thinking "oh yes, I know so many problems that can be solved by hot patching the running kernel" because honestly getting the act of patching the physical code itself is only the start of your troubles.
