Well, I believe the problem is not really the path but how the scripts
in casper are implemented. If we don't use GNU options which are not
implemented in the static binaries inside the initramfs, we have
nothing to worry about.

Yes, but this is a problem of the person who writes the scripts. I
mean, if that person take care of not to use software that is not in
the initrd, or run those through a chroot, nothing bad should happen.

I'm totally agree with you in this point. If casper need something
from the distro it should get through chroot.
