Eevee shadow maps for animations improvement..?

I know Eevee is still in preproduction but the shadow maps eevee is generating currently are Ok for still frames but not for animations. The shadows jitter a bit with camera movement. Are they still under improvement for 2.8 release.? or are they done so that they can concentrate on other aspects of 2.8.. I mean i read that Eevee is essentially being made as a preview renderer for viewport. For that purpose, that jitter might not matter much..
