That's easy. Look how much code kvm_getswapinfo() is and tell me
that you want to waste that memory in the kernel.

You can boot with a stripped kernel and then point the system's notion
of the kernel binary to a non-stripped version.
That doesn't handle permissions, but getting deep-down swap information
is not something any standard utility ever needs to do. It isn't something
like getting the load average, which utilities may legitimately need.
For that reason, I see no problem leaving kvm_getswapinfo() in libkvm.
