I would rather say this justifies breaking the freeze. Think about an user updating to 12.0... and having a 11.x jail inside (maybe as a first step before updating the jail itself, or not at all because of a bug in a 12.0 library he haven't found but is hitting the user). We want him to be able to have top working, don't we?
