Allowing a collaborator to publish changes to the staging site would enable a public preview, similar to WordPress. A lot of my clients need to get stakeholder approval on changes before they are published. Currently, this is only possible when the designer publishes to the staging site. It would be nice to give collaborators this ability so the designer isn't bothered with such a small request, especially when the changes don't require the designer to get involved. I've had some clients complain that they don't have the freedom to do a public preview (for other people to review) in Webflow like you can in WordPress.
