LT3045-1 - Can PGFB Pin Be Connected To OUT If Power Good Is Not Used?

Page 13 of the LT3045-1 datasheet says: "Tie PGFB to IN if power good and fast start-up functionalities are not needed."  Can the PGFB pin instead be tied to OUT if the power good functionality is not needed?

    The designer adds this input:

      "If their output voltage is above 0.3V, then they can tie the PGFB pin to OUT to disable PGFB functionality. But just note that during startup, as VOUT is ramping up from 0V, for a short period while VOUT is below 0.3V, the PGFB functionality may be engaged. But for most apps that is not a problem."
