"Point Crease," a.k.a. Edge Crease but for Grease Pencil

Point Crease would let users mark specific points with a "Crease" value, between 0% and 100%, the same as Edge Crease currently operates. Points marked as 100% Creased would completely skip the smoothing step of the Subdivision modifier, similar to how Creased Edges skip the smoothing step of the Subdivision Surface modifier.

Currently, you can fake this by adding extra points, but it takes about 10-20 seconds per point, at best, and you have to be careful lining them up by hand, since the only way to add a point mid-stroke is by selecting two points and doing a Subdivide, which by definition is nowhere near the location or thickness of the point you're trying to Crease.

Point Crease would greatly enhance the robustness of the Subdivision tool, speed workflows, and encourage new workflows, for all the same reasons that Edge Crease is desirable. The one difference is that Point Crease is arguably much more ubiquitous in 2D, as even soft, organic subjects such as humans, cloth and leaves require multiple sharp points in order to draw them.
