I could similarly counter that with a rhetorical question: "What are the advantages of moving to a new version of Redactor or <insert other editor here>?"
It's probably not the best time to have this conversation, but I thought it was useful to point out that the reasons for desiring an updated version of Redactor were somewhat flawed. You want tables, but a new version of Redactor won't give you that automatically.
Ultimately, if there are advantages of moving to a different editor, we will, if there's not, we won't. For now, we'll have to wait and see
