This bug is about Emacs getting "stuck" while scrolling, or scrolling erratically, not about miscalculation of the thumb size, right? I may be misremembering, but AFAIR that variable was introduced because some people actually _like_ the current default behavior wrt calculating the size of the scroll-bar thumb. Emacs should not get stuck scrolling, of course, but I cannot reproduce that on my system, so someone will have to investigate and tell why scrolling gets stuck or scrolls erratically in some situations when scroll-bar-adjust-thumb-portion is non-nil. Or maybe I misunderstand what erratic scrolling is being alluded to here.
