I'll reword this - "is it beneficial to stiffen the forend of a synthetic stock?"
Yes. If your forend is flexing, especially if it's able to touch the barrel, then you need to stiffen it.
I'd highly recommend pillar blocking and bedding the action at the same time, to ensure there's no flexion of the stock within the supporting area, and to ensure no tolerance for movement.
