Lightning use and applications

I’m just generally curious how many people actively use, continue to use, or have stopped using PyTorch Lightning? I like the idea from an implementation perspective, but forcing a team to learn another framework always feels like friction. The fine grain control with pytorch is what I want, but the collaboration and ease of experimentation with lighting is useful. Please share your thoughts, pros and cons and if you use lighting for experimentation, or prefer to build your own tools. Thanks!
