Juosan Division
Rules:
1. Standard: Normal sudoku rules apply.
2. Juosan: Some cells must be shaded such that no column contains a run of three or more adjacent shaded cells, and no row contains a run of three or more adjacent unshaded cells.
3. Divided Killer: In each cage, the clue in the top left corner gives either the sum of the unshaded cells, or the sum of the shaded cells. Digits may not repeat in a cage.
Solution code: Rows 1 and 4

That was fun. Thanks, @ Jay Dyer :). Indeed, this one deserves many more solves.

I liked it! It took me around an hour, but I'm usually very slow, so I rated it a 3/5 difficulty.
I'm surprised this has this few solves. I also published some sudokus with shading twists and they don't get solved either.
