     * @dev A side-effect of using this guard is that the guarded function can no longer be called as part of the Quark wallet
     *      callback flow. This is because the fallback in Quark wallet makes a `delegatecall` instead of a `callcode`. The
     *      guarded function would still be able to be called if a calling contract calls into the Quark wallet fallback using
