I wasn't talking about being able to follow a function pointer, but about
being able to see what's happening and not guess at the possible
semantics.

This is not the entire reasoning for removal, I was specifically 
addressing burden on core kernel maintainers.

There's also issues of inappropriate LSMs being submitted, having an
essentially unused infrastructure in the kernel at all, and forcing
SELinux to always use a generic infrastructure when it's not always the
best way.
