Of course everyone will eventually have WebGL-enabled hardware, but they won’t always be looking at 3D displays. Lots of AGI customers need to look at web-based graphs and grids and such, and it would be good for both customers and Cesium if those 2D products were also powered by JulianDates and CZML. They want to be certain the dates and data are handled the same, be it in a simple flat list or on the 3D globe.
Can you estimate level of effort for this? Does it seem like a good idea?
