怎么没有分层架构和COLA了？

**Describe what problem you have encountered**
应用架构之前还有分层架构和COLA，现在只剩了单模块和MVC架构。我想使用之前的分层架构，请问如何使用？

Before application architecture, there were also layered architecture and COLA, but now only single-module and MVC architecture remain. I want to use the previous layered architecture, so how can I use it?


Start by checking the application-architecture options exposed by the initializer and the project's history for the removed layered and COLA choices. Confirm whether those architectures are still supported and determine whether the expected outcome is restoring the choices or documenting how to use them.
