Tree shaking and barrel file from libraries

[MLiapkalo]

To start with, here's a minimal repo where you can see the behaviour I'm going to describe: repo
And here's the nx graph of workspace from repo:

My question is how can I perform tree shaking on barrel files from data-access libraries? Running webpack-bundle-analyzer(run nx analyze host inside the workspace from provided repo) shows that everything from data-access ends up in initial bundle(or am I misinterpreting the results?). I understand that barrel files from data-access libraries re-export every module the lib has, but I was expecting tree shaking come into action.

Output of nx analyze host:

Both books-data-access and users-data-access libraries have sideEffects: false in their package.json files and I use only a single module from each data-access lib inside host.
