아직 러프하게 작업 중이시기도 하고 이미 염두해두고 계실 수도 있겠습니다만, 제 생각을 정리할 겸 미리 몇 자 적어봅니다.

1. mm component를 try-except 구문을 이용하여 import 해서 쓰는 방향성에 대해서는 동의합니다.
2. 하나의 class 안에 if branch를 걸어서 mmcv와 mmengine을 구분하는 것은 로직을 복잡하게 보이도록 만듭니다. class 두 개를 각각 구현하시고 try-except 구문을 이용해 동적으로 import 하는 방식을 차용한다면 mmcv 및 mmengine 서로의 구현을 더욱 명료하게 보일 수 있을 듯합니다.

예시 1)

# at /mm/tasks/mmdet.py
if HAS_MMENGINE:  # or MMCV_VERSION > 2.0.0
  @TASKS.register_module()
  class MMDetection:
    # mmengine based implementation ...
else:
  @TASKS.register_module()
  class MMDetection:
    # mmcv based implementation ...

예시 2)

# folder
/mm/tasks
  - ...
  - mmtrainbase.py
  - mmcv
    - mmdet.py
  - mmengine
    - mmdet.py

# at /mm/tasks/__init__.py
import ...
try:
  import mmengine
  from .mmengine import MMDetection
except:
  import mmcv
  from .mmcv import MMDetection
__all__ = [..., 'MMDetection', ...]
