Metering tied to eye tracking

In the Canon pro DSLRs like the 1D, 1Ds, 1D X models, the user could switch to spot metering and tie it to the focus point. I've wanted that feature for the EOS R5 but I'm wondering if it doesn't already have it.

I've just spent the weekend at North Texas Irish Festival photographing musicians while they perform. This is the 2nd year that I've had the R5 but it is the first time I've had the "dual back button focus" implemented. I swapped the two buttons. The normal AF button does eye AF while the star button does the selected AF mode which I have set to one point. I did this because the AF button is more comfortable to press while also firing the shutter button and I was using eye AF much more than normal AF.

I also have exposure simulation set.

I noticed that while I push the eye AF button and the camera has not yet locked onto the eye, the exposure (in this case) was darker picking up on the white background which was the overall scene. But when the camera picked up on the eye and the AF locked onto the musician's eye, the exposure simulated in the view finder would change such that the eye was also properly exposed.

Has anyone else noticed this or am I daft?

All Canons have had this feature for many years. With the standard metering mode, the metering is biased towards the selected AF point. How much of a bias might have changed over the years. With each new camera I get, I find the metering algorithms to be improved. The bias is not as much as treating the AF point as the spot in spot metering, but it's often enough to overcome a fair amount of mismatch with the background.
