It doesn’t let you generate addresses ? Yeah there’s no technical reason why it couldn’t. It’s just bip32 which is completely independent from anything onchain/syncing.

It’s really hard to make changes to core since theres a lot of cruft and everyone is overly cautious of merging stuff. So it may not have the optimal wallet experience.

It’s great for coinselection and working with watchonly wallets with hardware wallet descriptors though once it’s synced. This is the *ideal* way to use core imo, but more advanced.

You don’t want keys on your computer, it’s best to just let core be a way to generate addresses from your hardware wallets and check balances.
