Talos makes it harder to backdoor the machine, because it’s radically open. An average RISC-V or ARM machine still contains various blobs and design compromises that make it harder to know that your code (or at least, code reviewed by you/the community at large) is the only thing running on the machine.

I wouldn’t recommend Talos to anyone who doesn’t have the need for it (and vast pockets to match), but I wish every ARM and RISC-V machine could be as open and trustable.
