Excluding cginc/shader files from Custom Assemblies (asmdef)

When using the new Custom Assemblies feature, one of the annoying things is that every single generated project in the C# solution seems to contain a reference to every single .shader and .cginc file. I've got, for instance, a directory with 4 files that I want to be a small assembly, but the generated project looks like this:



The circled things are the only files that should be in the generated assembly. I know there's a way to show certain files in the assemblies in the Project Settings under Editor:



But at some point I think .shader and .cginc and one other type got included by default in EVERY project. Since I, as a developer almost never work with the shaders, I'd love to not have the shaders show up in every single project that's generated. It clutters the view and makes it really annoying.

Is there a way to make the C# projects NOT include those additional files?

Thanks

 

According to the following forum post, the Visual Studio Tools for Unity team is working on a fix:

Are there any news? at least Unity 2017.4.1f1 and Visual Studio 15.6.7 still have this issue.

 

I use the attached script to sanitize the solution. It leaves one instance of every duplicated file in its actual project, and can exclude reference and files all together.
