My own current privacy roadmap (much lighter on L1 changes, but also more limited in its consequences): https://ethereum-magicians.org/t/a-maximally-simple-l1-privacy-roadmap/23459

Highly encourage people to read both!

Ethereum has made far too many “significant convenience sacrifices”

If the app addresses are deterministically linked to your seed phrase and primary address it’s a step up from the current privy and smart wallet fragmentation where you barely own your keys and they are spread out over many secrets.

Seems like privacy could be difficult to preserve in that structure

It shouldn’t be, it’s pretty much how bitcoin works. Most privacy preserving wallets generate a new unused address for every transaction for privacy. Instead it would be app specific, perhaps with salt logic to get the same address from scratch each time. The real problem is funding each address without linking.
