Why isn't Hyperfocus an option on AF modes?

Hello all.  When I travel I'm a bit of a run-and-gun shooter because I travel with travel agencies and don't have much time to sit wait for the right moment or fiddle around with the setting. In Switzerland, I tried to set the hyperfocus distance on several shots, but I seemed to fail after reviewing my shots.  I usually take my EOS R6 and RF24-105L and my RF15-35L lens on the trips and switch between the two.  

I'm a bit perplexed with the sophistication of today's mirrorless cameras and RF lenses why there isn't an HF (Hyperfocus) setting as an option on the AF modes?  The RF mount promised much more information would be available to the camera.  The user guide for the R6 is silent on achieving hyperfocus.  It seems all the information is there to support this feature.  Face & eye detection, I am sure was much more difficult to implement.

What am I missing??? 

I'm I the only one struggling with hyperfocus?

How can we petition for an HF focus mode?

Because AF is so good, there is not much call for hyperfocus.

Also, hyperfocus cannot be an "AF mode" because it depends on the Aperture, which is not set until *after* AF is complete.

Agree, AF has come a long way.  

I do not mean to come across as lecturing.  But HF is much more than a focus point.  HF distance is the distance in which we can focus our camera to achieve the greatest or deepest depth of field. The hyperfocal distance depends on our Sensor size, Focal length, and Aperture area.  Is HF a thing of the past? 

For the actual implementation of the solution let's leave it to the Canon programmers and usability experts.

The hyperfocal distance cannot be defined without first defining circle of confusion. The circle of confusion depends upon print size and viewing distance and vision ability of the person viewing the photo which are not usually known at the time the photo is made. If a standard circle of confusion is used, then one must use standard print size, standard viewing distance, and have standard vision ability.

(Johnrmoyer) If so, what's the purpose of all the HF calculators?

They all assume or specify a CoC, honest ones should tell you.

That is not something a camera can assume, since the image can be used in many different ways, at many different sizes.

In ancient times, a print size was assumed.  When most prints were no larger than 8x10 inches and if hung in a gallery people could not stand too close and assuming some typical visual acuity, one could use the depth of field marks on the manual lens on a film camera and get close to the right focus distance.
