Dunno, we see plenty of people starting to use it. If you are savvy enough to run a jail/sandbox to begin with then you must be accustomed to a CLI already, so it doesn’t seem that big of a lift to me.
I think somebody around here might have even done video tutorials about it? But I think its someone obscure who never has posted it more than once, you may need to go hunting to find it.
In the meantime, this thread has really veered off topic, so I’ll close it down for now, please open a new one if we want to debate docker, jails, or whatever other bike-sheds need addressing
