The decorator downlevel transform is never used for actual class decorators because Angular class decorators rely on immediate execution for JIT. Initially we also supported downleveling of class decorators for View Engine library output, but libraries are shipped using partial compilation output and are not using this transform anymore. The transform is exclusively used for JIT processing, commonly for test files to help ease temporal dead-zone/forward-ref issues. We can remove the class decorator downlevel logic to remove technical debt. PR Close #49351 |

This is a directory defining the @angular/compiler-cli/private entry-point. The entry-point can be used to
expose code that is needed by other Angular framework packages, without having to expose code through the primary
entry-point.
The primary entry-point has a couple of downsides when it comes to cross-package imports:
- It exports various other things that will end up creating additional type dependencies. e.g. when
the Angular localize package relies on it, it might end up accidentally relying on
@types/node. - The primary entry-point has a larger build graph, slowing down local development as much more things can invalidate the dependent targets. A smaller subset leads to faster incremental builds.
