They did it for a 1915 Cracker Jack I recently submitted. You'd think SCG would have the right-fitting gaskets for CJs (as they always used to). I don't love the look either, especially when the card is tilting or off-center.
But in most cases, I've been able to center the card by tapping the edge of the slab on a hard/rigid surface. It takes a little practice, but in most cases you can get it to move and improve its aesthetics significantly.
I hate that SGC is now doing this. The custom-fit gaskets were a huge advantage that SGC had over PSA. At least SGCs still lay flat and don't crumple up like the "baggies" PSA uses.
