Question: is there specific reason for tsup?

Hi guys. So I have a question, is there any specific reason you use tsup? The build can be done with just vite. One config less for you. Will you accept PR with this change?

My understanding is that Rollup and TSup make it easy to have multiple build configs in one file, but Vite doesn't. There can be up to four different builds in a Storybook addon, and it's nice to have them all in a single file.
