Additional code can be added to notify the user of an update as well. Many coins have done this in the past, and it works well.

I saw on the forum a message from Rijk that there is a notifier already implemented in the wallet. Don't know how it works, but it seems to be there.
Perfect. Add the version limiting/banning code, and you have a successful rollout. In fact, at that point, all the connections on the seeds page would be the correct version.
I'm excited. I know it's not set in stone, but I'm looking forward to any changes the devs make.
