Now you’re assuming that the group that would switch is bigger than the group that appreciates the tabs at the bottom. I doubt that the tabs at the bottom are the main reason people wouldn’t switch to KDE.
Not only this, but who exactly uses Konsole? It's certainly not grandma, who you set up with a KDE laptop. She's not going to know what to do with the command line, and even if she did need to use it for some weird reason one day under your direction, she sure as hell isn't going to open multiple tabs in Konsole.
The people using Konsole are already the highly technical people, and therefore probably not newbie users.
