Geometry Nodes: Add Delete Geometry Node
This node is similar to the mask modifier, but it deletes the elements
of the geometry corresponding to the selection, which is retrieved as
a boolean attribute. The node currently supports both mesh and point
cloud data. For meshes, which elements are deleted depends on the
domain of the input selection attribute, just like how behavior depends
on the selection mode in mesh edit mode.
In the future this node will support curve data, and ideally volume
data in some way.
