Thanks for PR dear @nathanchase. Wondering is it worth to wait for sharp feature to be stable first?

Do you have some more context why it is in experimental state?

I don't have any knowledge of why it's experimental. I just know that I have an immediate use case for it with https://github.com/nuxt/image to make all images with a solid white background become transparent backgrounds. I happened to notice it wasn't wired up to sharp's implementation, so this was just meant as a means of connecting to the unflatten functionality that already exists so that I could use it.

For what it's worth, unflatten has been in sharp since April 2023.
