Something that has come up a few times is the possibility of adding a node that adds a single point.
That might be a curve point, mesh vertex, or point cloud point.

Currently this is possible with the mesh line node, but having a more explicit way to add a single point might be helpful.

The problem is, a single point is always a special case of other operations, so we have to decide whether it is worth having another node.

Previously, there was need for a "Single Point" node because we didn't have #92964 (Node to create a single instance from geometry).
So often the lack of this node exposes a design flaw in the system. At that point we should really fix the design flaw rather than add a workaround.

Details on the proposed node:

Vector input
Geometry output
Possibly a toggle for the type (mesh/curve/point)
Name: "Single Point"
Category: Probably "Point"

In light of D15198, another design for this node becomes more obvious:

In this case the Position and Radius input can only depend on the Index field input.

I'll update the patch
