I recently noticed this new tool, which must have only been around since about Blender 4.2 (as I can't find mention of it in older docs). It allows you to slice and cut shapes, and also create new geometry. But it also lets you make more elaborate Face Sets, Masks, and even hide geo while sculpting. Quite a useful tool indeed.
