Regression: some URP shaders have too many variants in 2021.2

Describe the bug Not sure if this is a regression in URP or in glTFast, I believe the former is more likely. When adding the glTFast shaders to the list of “Always included” shaders, building to Android on 2021.2.0f1 fails with the error message: Shader Graphs/glTF-metallic-Premultiply-double has too many Shader variants(201326592).To resolve this, go to Project Settings > Graphics and remove this Shader from the Always Included Shaders list.For more explicit control over how Unity includes specific Shader variants in a build, use a ShaderVariantCollection.

As the goal for the glTFast shaders would indeed be to be always included (so that all models can be loaded), I think this is a blocker for using glTFast for runtime loading on 2021.2 right now.

To Reproduce Steps to reproduce the behavior:

1. make a project on 2021.2 with URP targeting Android
2. add the glTFast shadergraph shaders to the list of always included shaders
3. try to build

Expected behavior Building works, actually error message prevents building

Closing, since this was fixed by the URP devs:

It’s now fixed in Universal RP 12.1.5 (2021.2.14f1), 13.1.6 (2022.1.0b10), 14.0.2 (2022.2.0a9), and above.
