if i understood that page, debug shell is... "exec" with a nicer .bashprofile and injected text editor binary???
It's an alternative to https://docs.docker.com/reference/cli/docker/debug/, which is also a paid feature.
Debugging slim or distroless images is quite the pain, so a tool like this is worth it if you're frequently working on such images.
It's installing additional packages which may not have been included in your base image.
> Debug Shell works by injecting a debugging environment using: > NixOS for a large package collection, and flexibility with filesystem paths
The debug shell feature alone makes it better than any alternative, and hopefully that subscription money is put towards more unique features.
