Welp, `cargo tree`, 100 nights and 100 coffees then it is

Yes!

I sometimes set up a script that runs several variations on 'cargo tree', as well as collects various stats on output binary sizes, lines of code, licenses, etc.

The output is written to a .txt file that gets checked-in. This allows me to easily observe the 'weight' of adding any new feature or dependency, and to keep an eye on the creep over time as the project evolves.

You will need something stronger than caffeine.
