The main reason for this is to give consistent results between the AP and Material Editor, where a placholder texture can be used if a texture is missing. Otherwise, you could get a placeholder texture in Material Editor and stale data in the runtime; this inconsistency would be confusing.
As a consequence, it is possible for example that the user could mess up the name of a property in a .material file and not notice the problem because it is now a warning instead of an error. If warnings-as-errors is desirable, you can enable the new "/O3DE/Atom/RPI/MaterialBuilder/WarningsAsErrors" registry setting.
