With #28594 we refactored the `@angular/compiler` slightly to allow opting out from external symbol re-exports which are enabled by default. Since symbol re-exports only benefit projects which have a very strict dependency enforcement, external symbols should not be re-exported by default as this could grow the size of factory files and cause unexpected behavior with Angular's AOT symbol resolving (e.g. see: #25644). Note that the common strict dependency enforcement for source files does still work with external symbol re-exports disabled, but there are also strict dependency checks that enforce strict module dependencies also for _generated files_ (such as the ngfactory files). This is how Google3 manages it's dependencies and therefore external symbol re-exports need to be enabled within Google3. Also "ngtsc" also does not provide any way of using external symbol re-exports, so this means that with this change, NGC can partially match the behavior of "ngtsc" then (unless explicitly opted-out). As mentioned before, internally at Google symbol re-exports need to be still enabled, so the `ng_module` Bazel rule will enable the symbol re-exports by default when running within Blaze. Fixes #25644. PR Close #28633
