When compared to a VM, yes. But shipping a separate userspace for each small app is still bloat. You can reuse software packages and runtime environments across apps. From an I/O, storage, and memory utilization point of view, it feels baffling to me that containers are so popular.

Why? It's not virtualization, it's containerization. It's using the host kennel.
Containers are fast.

"bloat" has always been the last resort criticism from someone who has nothing valid. Containers are incredibly light, start very rapidly, and have such low overhead in general that the entire industry has been using them.
Docker containers also do reuse shared components, layers that are shared between containers are not redownloaded. The stuff that's unique at the bottom is basically just going to be the app you want to run.
