Be cautious about Nodes with z-coordinate

[DanielTollenaar]

What
Received a model with mixed x,y and x,y,z Point geometries in the node-table, e.g.:

Adding an edge between these to nodes will cause a validation-error:

Why
LineString cannot be drawn between x,y Point and x,y,z Point

How
Suggest to drop z-coordinate in add-API, reading and writing so user doesn't need to drop z-coordinate all the time

Edit 1
This code I use in Ribasim-NL now:

def edge(point_from: Point, point_to: Point) -> LineString:
    """Create a LineString geometry between two Point geometries, dropping z-coordinate if any

    Args:
        point_from (Point): _description_
        point_to (Point): _description_

    Returns
    -------
        LineString: LineString without z-coordinate
    """
    if point_from.has_z:
        point_from = Point(point_from.x, point_from.y)
    if point_to.has_z:
        point_to = Point(point_to.x, point_to.y)
    return LineString((point_from, point_to))
