Steam Frame Eye Tracking

Hello! So.. I've been thinking about getting a steam frame as an upgrade from my Q3, which I use only with babbalonia FT.

The thing is that I don't really know how good the eye tracking is gonna be compared to the quest pro for example, a vr headset that I've been also looking for.

Some months ago I saw a post regarding that the steam frame won't have eyebrow tracking and maybe not even blinking? If I remember correctly.. so I'd like to know if something has changed or if someone it's on kind of the same situation as me.
