What would the FFF have to do in order to be competative?

What I think would be an interesting version would be a chip with four layers with the bottom one being a very thick capturing mainly IR. It could be made perform quite a bit better in IR than current conventional cameras even when IR converted (as the photodiodes don't go deep enough to the silicon).

Yes, that might perhaps even improve the differentiation of 3 primary colors, wouldn't it?

Not if the layer depths remain unchanged, as they have been since the very beginning ...

I thought the color separation diagram and the 3x3 layer data transformation matrix suggest that additional layers would also improve the accuracy of 3 primary colors, due to the probabilistic nature of the process. A 4x4 transformation matric would improve all 4 "colors" (the 4th being infrared).

Maybe I have misunderstood something.

If that's true, I'm surprised they've never tried a 4-layer sensor before. They wouldn't need to use an IR-blocking filter, and the camera would be capable of IR photography without modification. In fact, every photo could be processed as an IR photo. How cool would that be?

I suspect there are diminishing returns and benefit-cost considerations that outsiders cannot evaluate properly. But such benefit-cost considerations can also change a bit over time, with new tech approaches.
