Yes Apple could do leagues more to improve testability of Safari; they're by far the worst in this area.
The broader point is that applications may perform or behave radically differently even under a Chrome monoculture. So you're still on the hook for platform-specific testing, if you actually care.
Unless you have SR-IOV setup this doesn’t tell you if the website is slow because of lack of GPU acceleration or something you could fix.
Still at least you can see if it actually works, unlike Safari.
