Description
The daiJoin contract may be caged, which means exit() is DoSed forever.
This is called in the psmWrapper buyGem(), legacyDaiJoin.exit(address(this), usdsInWad);, so it would be forever DoSed as there is no way to 'uncage'.
Recommendation
It's possible to set a new Psm in the Sky strategy but it is something to keep in mind.
