I'm a little torn on this.
I'd love to see more adventures of Ahsoka, Sabine, and Ezra. These were all fun characters.
On the other hand I'm okay with loose ends, and am worried about having everything tied up and fitting nicely with the Episode 7-9 story. I'm not sure I want them definitively killed off or pulled back in to the Rey / Resistance story line.
If they can find a way to pull Ahsoka, Ezra, and Thrawn back in to the post E9 story, that would potentially be cool, but I don't think its necessary.
