Instances of Prefabs From ScriptableObjects Have Black Material, Bad Custom Shader

Here's what our project looks like:

Material > Scriptable Object > Asset Bundle
Shader > Scriptable Object > Asset Bundle
Prefab > Scriptable Object > Asset Bundle

Right now all of the Instantiated (not hierarchy!) clones of our Prefab in the Scriptable Object, whether we manually assign it a material or it has a reference to the Material in the Scriptable Object, looks black.

We can get them to show up by adding this Shader to "Always Included Shaders" and then using Shader.Find("Custom/OurCustomShader") and assigning it to the material.shader ... but should this really be necessary?

Here are other people who have been experiencing this issue for over 5 years. Just incredulous that Unity had not fixed this yet / this is the accepted way to do this...
