The sanitizer runtime is not nearly as complex as the Fil-C runtime.
Sanitizers don't have to deal with:

Oh and it's not clear if the current revision of the capability model would work with memory mapped IO: https://fil-c.org/invisicaps
Does fil-c have a way of disabling the capability model for regions of code? (Rust's `unsafe` blocks come to mind).
Maybe if I ask enough stupid questions, you'll get pissed and get the kernel to build/work with fil-c just to prove a stranger on the internet wrong. :P
