…@angular/build` builders Previously, all builder options that were of type array were set to a default empty array even if there was no explicit default defined within the schema. This can be problematic for options that have differing behavior based on their presence such as runtime calculated defaults. The implicit defaulting behavior was also not aligned with the generated schema types which resulted in additional type safety and initialization regardless. As a result, the implicit behavior was effectively redundant in most cases. Since this change could be breaking for third-party builders, the removal of this behavior is currently limited to the `@angular/build` package.
