Migration of Dropbox
As mentioned previously, this is not on our roadmap for the time being.
I just wanted to mention that there is a quick workaround which is to export the folders and documents from Dropbox to a file system and then import them into SharePoint using Sharegate with the Import from File Share option.

Dropbox would be a great addition, even if it is means it is a "2 step process", especially dropbox for business users. The problem with your solution to move first to a file erver is that all users must need to set up a sync with dropbox. You can only setup one sync.
So we need an method to retrieve all users and automatically create all user folders on a file server
