Yes importing fresh addresses without rescanning will be done. The difficult thing I'm thinking about is synchronizing a wallet for the first time, maybe when it's being recovered from backup.

Good job on the pruned JoinMarket node(!) I assume you compiled your own version of Core with the wallet enabled?
I'm more worried about people who desire privacy (those doing repeated coinjoins again and again) and how they would manage. Bitcoin Core with a fully downloaded blockchain is the most private way of using things but it required 40gb+ of free hard disk space.

I may be wrong but since pruned nodes switch off the NODE_NETWORK flag they are not able to upload information about transactions or blocks to the p2p network.
