The current logic of the CDPVault, allows for the pausing of liquidations, but not of repayments of debt.
Now, whereas this logic is safe and best for the user, this is extremely bad for the protocol; considering that naturally the protocol is to be set in a paused state when a black swan event occurs and until this gets sorted out it wouldnt be unpaused. Due to this, however, a very large loan thats now liquidatable and accruing bad debt can never get liquidated, because the inherited whenNotPaused modifier always causes it to revert.
Protocol would be put in an unwanted state. When the Vault is paused and large loans start accruing bad debt since liquidating these loans would not work.
Consider removing the whenNotPaused from the liquidation logic.
