Then we'd want to look at 'where' the flutter occurs.
Side body deformation could affect yaw moments and directional stability, depending on velocity, winds, gusts, etc..
If it's anywhere in the aft-body, it could trigger separation and induced-lift, laterally, or vertically.
Cyclic deformation could induce Karman vortex street-esque phenomena, tail wagging the dog.
Aeroelasticity implies unstable drag coefficient. I don't know how that could ever be beneficial.
