PKGBASE in ZFS Boot Environments World

We know that 'pkg delete -afy' will delete all PKGBASE packages without asking ... but that will also render ZFS Boot Environments USELESS as there is no loader(8) anymore to show the ZFS boot menu for BE selection.

OK ls boot
boot
 d  zfs
 d  efi
    loader.conf
    entropy
 d  firmware

My proposal - always keep a MINIMUM set of files allowing to show loader(8) boot menu - so anyone - even after wiping their FreeBSD system with pkg(8) - will be able to boot into other backup ZFS Boot Environment.
