This exactly. NVN is lower level than dx12/Vulkan and is probably more comparable to Sony's graphics APIs in terms of how low level it is.* And even if the NVN version itself remained the same, consoles use precompiled shaders as you say, so unless you keep that API stable between generations as well you are going to need to do some form of translation between the new and old APIs. * I've never used NVN but I imagine it must be very low level otherwise developers would not be using it instead of Vulkan which is also supported by the Switch. Feel free to correct me here or clarify if I'm right on this.
