You seriously haven't seen a program that provides split panes? Never used an IDE that allows you to see multiple files at the same time in the same window, in a grid of panes, side by side?
Because I don't want to manage 4 windows tiled like 4 panes - I want to manage a single window with 4 panes. What happens if I close one of 4? Now I have a gap that an related or unrelated window will fill or it'll be a wasted space - this doesn't happen in case of split panes because the other panes will expand to take the space. I logically group my work in separate windows - so in a split pane setup, once I'm done, I close a single window instead of having to close separate windows one by one. If I have a 4x2 grid in your tiling-WM-is-the-truth world, you expect me to close 8 windows one by one?

Sure, if you lack imagination, everything must be feeling like a distraction.
