I would go more for something like "deadinuse". Saying they are
unremovable isn't very helpful because it doesn't lead the user to
knowing why. If the name gives some suggestion as to why they are
unremovable--in this case that they are still potentially visible and
usable by old queries--that would be a useful naming improvement to me.
