I normally do that as well, but some people prefer to mount s3 as a file system like mentioned in this post. I’ve had to use it for work when my boss required it. I’d personally use the CLI for everything.

What benefits would this have over something like s3fs? I’ve never had issues with that, but it doesn’t cover all the use cases you outlined. There are robust alternatives for SSH as well that have connection error monitoring to avoid the situation you outlined.
