The problem is the “more”. SELinux is extremely flexible and does what the configuration tells it to do. And it does not compose well. Want to point whateverd at /var/lib/whatever? Probably works if the distro packages are correct. Want to make /var/lib/whatever be a symlink? Probably does not do what you expect. Want to run a different daemon that accesses /var/lib/whatever or mount it into a container? Good luck. Want to run a second copy of the distro’s whateverd and point it at a different directory? The result depends on how the policy works.

And worst: want to understand what the actual security properties of your policy are? The answer is buried very, very deep.
