It would make the chimney usable and ensure it flows safely? I dont think the chimney will fall over soon, but that's why i requested a better photo..
The issue in question isn't the chimney at all it is the joint between the firebox and the brick facing. It may need a liner as well we have no idea.

If the chimney has separated from the house or moved that much in the photo and no repairs have been made....and has tile stacked going up... I can ensure you those joints have failed. That's why I suggested a liner for the new owners. Let the new owners repair the firebox and mortar.

I can all but guarantee the chimney has not moved the face has probably because the face and hearth extension are not on an integral slab they are supported by wood framing. I see this pretty often if the chimney itself was separating from the house by 1/4" per foot as the gap in the picture shows I am sure the homeowner would have noticed and the home inspector certainly would have called that out. In addition if the actual chimney was moving that much a liner certainly wouldn't make it safe. It would need underpinning or torn down.

OK, chimney guy came by. Said all looks good, the fireplace isn't pulling away from the house. However the gap shouldn't be filled with mortar, it needs fireproof insulation and silicone over that. Cheap fix, $350.

Silicone is not appropriate at all . And the face is pulling away badly there is a structural problem there

Asking again, is the gap the same from top to bottom or does it get larger at the top of the chimney?

The chimney is not moving as I thought according to the sweep

When I was building my log cabin, I also built a stone fireplace. The county inspector came out when all the foundation for the house and fireplace had been dug, but before the concrete had been poured.
I made a massive fireplace foundation for the concrete, it was 3 feet wider and 3 feet longer than the fireplace, and it was 15 inches deep.
The inspector told me "You got carried away on this fireplace foundation. It is way too big."
And I said "Have you ever seen a fireplace with an inadequate foundation, so that after the house was built, the fireplace began to pull away from the house."
The inspector gave in at that point he knew I had him.
That fireplace is pictured at left, it is 25 years old and still straight and true.
