Public Composables with PreviewParameter

[remcomokveld]

The explanation for ComposePreviewPublic is that a composable should not be public if its only purpose is to be a preview.

This rules seems to flag composables that have @Preview and a @PreviewParameters annotation. I'm curious why those composable specifically qualify as something that is only there for preview purposes?

I thought the nice thing about @PreviewParameter is so that you don't need to have a separate composable that exists just for Preview because you can add previews to "production composables" by defining what states they can have.
