What problem does this feature solve?

Is there any plan to provide migration for angular similary to other already available on docs?

What does the proposed API of configuration look like?

Our product heavily relies on Angular, and we are currently experiencing long build times. We're using a custom Angular builder, but this isn't meeting our needs effectively.
I would like to explore using Rspack as a potential solution to improve our build times. I believe that by working together as a team, we can evaluate whether Rspack meets our requirements and implement it if it proves beneficial.

Your collaboration on this initiative would be greatly appreciated. Anyone have the same problem ? Let's work together !

Thank you!
