That makes perfect sense and it's definitely true that sometimes the hotfix is not a bug in your code (which can be solved by a rollback) but instead having to patch a problem in a dependent system. But that seems orthogonal to the container issue. Shelling into a live server and changing something only works if you have the entire build toolchain on the production server which hasn't generally been the case in my experience. Even if you aren't using containers you still need to build artifacts and deploy them. It's just that you are deploying binary artifacts instead of containers. It doesn't seem like the container builds are the real long pole in that process.
