Since Bitcoin Core 0.17 the startup option upgradewallet has been available, allowing users to upgrade old legacy wallets to HD wallets.
However many users with non-HD wallets are yet to upgrade their wallet, to reduce complexity, and or various issues related to non-HD wallets, I am wondering if it may be a good idea to require users to upgrade.
Two different ways of implementing this (off the top of my head):
- when all addresses in a keypool are marked used, automatically upgrade wallet and notify user to make a backup.
- on startup upgrade wallet and notify user to make a backup
Are there any reasons for why Bitcoin Core doesn't already do this?
