Swaybar for regular driving?

Another example of this is TRUE Mcpherson strut front suspension (in circa 1980 Mazda GLC), where a sort of normal heavy looking front sway bar locates the bottom of the strut/spindle carrier...thereby serving both locationg and springing functions in one piece.
So, Yaris has anti-sway at both ends.
91 fwd Corolla Wagon has no anti-sway, and softer spring rates. Works fine in all driving I've done. Just doesn't feel like a go-cart. Maybe better than Yaris on the high-crown gravel roads. (If anything I could see adding some light anti-sway at this Corolla's rear only for better peg-leg-differential traction.)
Corolla got a version of this suspension after Tercel. (Stated reason was improved trunk space.) A circa 2005 one I saw had a visible solid bar inside a U-shaped channel for the cross beam. Tercel had just the U. I think rabbit had a T-section. Looks like yaris has a closed tube in a shape that is relatively soft in torsion?

This is the second time you have posted this (previously in a different thread) and you are still wrong. The Yaris DOES NOT have IRS, nor does the Yaris have an integral rear sway bar. I don't know where your getting this from but it simply is not true.
