Those things scare me, the bars over the doors. First of all they are merely bolted to the B-pillar hoop on a thin metal mount. And the other end is bolted to sheetmetal, and usually rusted sheetmetal at that. In any direction other than straight back, that w.s. frame is going to collapse and push that bar in some other direction, quite possibly down into the driver or front passenger. Those bars were strictly for looks, and maybe some assistance getting in.
The rear "family" bars are pretty much the same and will fold in sideways towards the rear seat. But putting a spreader between is a good improvement. As long as it's not just an add on bar that clamps on, because that will just rotate around the "family bar" legs with a side impact and allow them to fold just as before.
I'm just not big on those Wrangler sport bars. They were no better than the Jeeps sport bar but potentially more dangerous.
We can always debate how the various bars hold up, and keep in mind there are variances of a slow tip over vs. a roll, or flat land roll vs. a sidehill roll, etc. But one thing is for sure, we don't get to pick when, where, and how the situation will happen! So plan ahead.
