As long as the layout only governs the x,y coordinates and leaves anchoring alone, the anchoring on the last item will win.
I think that can be a reasonable compromise. This is already how the Row/Column already function. (apart from the fact that the y coordinate is always 0 for rows etc).

Yes, you are right about that. I think my proposal would only really with splitters and row/column layouts. So it might not be such a good idea after all.
