This is research. You should be focusing on "what's new, and is it interesting" not "is the thing they made a good product".
That said, Li-S typically looks good with respect to potential cost if mass produced (cheap materials), and density metrics. The papers abstract has absurdly good things to say about charge rates. All-solid batteries are typically going to be very safe. So at a glance this research is at least in a very commercializable direction.

Sulfur melts at 115 °C though, so when it overheats, it's not solid anymore. But then, it's apparently not just sulfur, but sulfur embedded in some other stuff, so who knows.
Here the sulfur is contained in some kind of borophosphate glass, which should have a significantly higher melting point.
