It's not something I see adding. The issue being that the the UI and rendering code is built around handling value ranges, which works well for the existing DEM sources, but the NLCD uses essentially random numbers. There's certainly no way to do a color gradient, and even shading all impervious surfaces with a certain color would take some work.
It's turned off at the moment, but I do have code that displays a layer colored by NLCD values, with no customization options.
Interesting, that makes sense why it wouldn’t work in the DEM layer.
I guess I wasn’t even considering using gradients, just symbolizing select landcover types with a specific color. For example, shading grassland as light green in order to better distinguish it from rock, which sometimes appears a similar shade of brown on sat photos. You do already give us plenty of ways to get that kind of information, though!
