I've flip-flopped on this a few times. I used to be solidly in the same
position as your statement, but after seeing the things the secure-boot
crowd want to lock down, there are a ton of places in the kernel that
would need additional root-proofing to avoid scribbling over kernel
memory.
In short though, yeah, expect fireworks right now, especially on bare-metal.
At the same time, just to increase coverage testing of a lot of
root-required functionality (like various network sockets that can't be
opened as a regular user) I added a --drop-privs mode to trinity a while
ago, so after the socket creation, it can't do anything _too_ crazy.
