Geometry Continuity Node for GN

I believe it would be a truly wonderful addition to geometry nodes to have a node that can detect disconnected islands of a mesh object, much like the connectivity node in Houdini. The node could have an integer slider starting from zero, where each integer corresponds to a mesh island and the resulting vertex id's could be fed into a predefined vertex group. This way, you could iterate through the island id's and have them behave in a certain way en masse. Or another usage could be to cut an object using a boolean node and move the vertices of one of the cut away islands. The possibilities are endless...
