Proposition for cross functional teams

Hi, I'm really happy to find to something like this. I've been giving a lot of thought on this lately.
I just needed your thoughts on this.

Take an hypothetical team of engineers that are organised based on certain feature that would be deployed both on the backend on client applications (web, mobile and via public APIs). So each team is responsible for the servers and client packages. How would their organise the code to reflects their team while allowing easy sharing of common packages between teams. Example would be a hashing library or a Hero component package.

Looking at your own structure, I'd say I could implement it in flat manner. No hierarchy. But, I'd want some sense of ownership for a package or feature
