It would really be nice to not have to require a daemon to make this program useful

c.f. https://github.com/TheTumultuousUnicornOfDarkness/CPU-X/wiki...

the daemon separates userspace from root domain, and ensures that the code running with root privileges is very small and easily auditable

Maybe I am dumb, but why does it have to be a daemon? Why not have the user process fork off the privileged binary to collect data and return the results through stdout?

Forking a process is not free and starting one every hundred of a millisecond* seems very expensive. *I'm do not know which frequency it updates the data but it's usually 1 sec to 0.1 sec.
