Depends on the style of photography. I tend to go for hyperfocal-distance landscapes using a 36 megapixel FF sensor. If you want to call that an edge case then I'd agree. I'm not too hung up on shallow DoF - it looks nice for a portrait or picture of your meal but I think there's always room for higher resolution sensors capturing a world of visual information (provided they can produce great dynamic range which a lot of recent/new high resolution FF sensors do). APS-C, similar to M4/3's 16-20 megapixel sweet spot, seems to be stuck at 24 megapixels for good dynamic range results.
