You would be better to try to reduce flare. There is reduced separation in the shadows. Fortunately, the reduced separation in shadows is not important to most viewers.

So you can't reduce exposure and expand development to compensate for flare.
But you can reduce exposure "knowing" that flare will bring up the shadows slightly. Going the other way is OK too. Any increased exposure will look like fogged negatives.
You can decrease the exposure until you feel you are on the toe of the curve. Then you are at the point where you are not making things better.
