so it wont really help in preventing highway wander during crosswinds?

Actually it does to one degree or another.

It should be understood that even on the highway, traveling in staight line, the suspension is constantly flexing and the end result is one side will hinder the flexing other with the sway bay installed and therefore, stiffen the suspension feel. Rarely does the road want to compress both sides of suspension equally.

Of course, one can argue just how much stiffer it will feel and also the 19mm vs the 23mm.
