In the past, I've toured these alternate, non-POSIX shells like Nushell. A lot of them (e.g. Powershell, Elvish) don't provide job control. I looked into how job control works and it's kind of a bother, so I see why they might have elided it. I wonder if multiplexing the terminal using tmux or screen is a good enough alternative the job control for many use-cases. You do lose state (i.e. environment variables, working directory), but if all you want to do is run something else maybe it's good enough.
I personally haven't tried living without job control though.
