From a documentation perspective, would it help to have the story name be more like ListWithHeading or something similar? Trying to think of when someone might be looking for how to do X (where X is adding a heading for a list) and having a story name that makes sense to them.

The terminology "NewGroupedHeadingAPI" feels very clear for maintainers but from a user perspective might not make as much sense.

Oh sorry I forgot to mention that I added these stories for dev/code review only to make the changes easily viewable. Since we are going to deprecate the title prop on ActionList.Group and our new API for providing group title is ActionList.GroupHeading, I was thinking to update the stories that use title prop with ActionList.GroupHeading such as GroupWithFilledTitle and GroupWithSubtleTitle. Would that be helpful and enough you think for consumers to find how to add group headings? Also do you think we should still keep stories with the title prop at all? 🤔

I'm going to take these stories back in this PR. I am thinking to do a follow up one that adds a @deprecated notation to the title prop and update all title usages with the new API in stories and docs. Let me know if there is any concern!

I'm not sure what our conventions are, but when would we use an empty handler for events versus using storybook actions?

This is a really good question. I am not really sure either. I find storybook actions useful when the story is about the action like the data table action stories you added are great examples for this use case in my opinion. The stories I added or the ones I mentioned here to update are not focusing on actions, they are focusing on semantics, visuals, and having group titles. This is why, I didn't worry about the action itself but I am more than happy to update them to use storybook actions if it is going to be helpful.
Re-thinking about it now, it is probably helpful to log something (storybook actions could be very beneficial in this case) when the click event is trigger at least so empty event handler isn't very helpful here.

What are your thoughts??
