Okachu, you gotta change your way you ask questions.
I understand you might need help, and we can help you, but you have to optimize the way you post.
- If you have a question, before posting it, ask it three times to yourself, then only when you feel it's relevant or potentially can help someone else. Then ask it.
- If you're experimenting with Unity or VAM, don't create 5 threads a day to ask random questions. Work, experiment, do things, gather a list of small random questions, then create a thread.
- If you have a question, look overall VAM assets, by creators you like. A bunch of questions can be answered by just looking at how things are done and released (beyond extremely technical questions).
Why am I saying this? Because of your current question which is literally containing the answer in the question.
- You saw many VAM tutorials saying you can export light with assets? But were they really that good? Did you see much asset doing that? Do YOU think it's a good idea?
- You removed the light for a reason YOU are explaining in that thread. Why would this be a bad idea if you have an actual valid opinion?
- If you're doing something that you feel "right" for your use case, and you feel is right for sharing on the hub, or even better, you feel is better than other releases and other suggestions... why wouldn't it be?
What I'm trying to say is trust yourself, don't always rely on people to give you the pointers especially for obvious questions that you can answer yourself with a tiny little bit of common sense.
To answer your question : no including lights in assets is a bad idea unless you're providing a way to disable it or customize it. There are ways to disable lights with some plugins on the hub. But it is extremely annoying to have components you don't need by default. So yes, you made the proper choice here, removing lights is the way to create clean assets
