They will definitely AF as-is, f/11 is fine for all DPAF, but I doubt you'll be able to add the extenders, especially the 2x, and have AF work (other than with a R5 or R6 that is).
Actually, I think you're wrong about that. Canon's official product pages for the extenders are now up, and they don't say anything about the extenders not working on R or RP.
It's not about the TC itself where there may be an issue; it is about the resulting open f-number. Canon says f/22 works on the R5 and R6, meaning that AF is reasonably fast and reliable by some standard. It is possible that the same f/22 will be more difficult for the R and RP, with more hunting in low light and low contrast.
EOS R actually has exactly the same low-light focusing spec (EV -6 @ F1.2) as R5, and only half a stop behind R6 (EV -6.5), which suggests that it shouldn't lag much the newer bodies in low-aperture focusing, if at all. But we'll see.
The question is will the R and RP focus at f/22, and I've never heard anything vaguely like that mentioned (just f/11, e./g. see the quote below). The issue is the size of the aperture rather than the amount of light you are getting.
"The AF points on the EOS R are compatible with maximum aperture f/11 at all AF positions (when used with a compatible lens and extender, such as the EF100-400mm f/4.5-5.6L IS II USM lens paired with a 2x extender). This makes AF possible even when shooting at a super-telephoto 800mm, dramatically expanding shooting possibilities for wildlife photographers."
F22 probably not. however, F22 is with a tele extender. F11 probably yes.
I seem to recall F16 being a limit, but to be honest after a while at this over the past week i'm lucky to remember my birthdate.
It still counts with an extender, take a f/5.6 lens and add a 2x you get f/11 and it won't AF on a DSLR that AFs to f/8.
AFAIK all Canon live-view went to f/11 (and possible a teeny bit more, 1/3 - 1/2 stop) prior to these cameras.

Fujifilm's X-H2 is a high-resolution stills and video camera, that sits alongside the high-speed X-H2S at the pinnacle of the company's range of X-mount APS-C mirrorless cameras. We dug into what it does and what it means.
Holy Stone produces dozens of low-cost drone models aimed at consumers. We look at the HS710 and HS175D to see if they stack up to other sub-250g offerings. Are these secretly great or more like toys?
It's small, light, cheap and extremely wide but is it any good?
After weeks with a production Fujifilm X-T5, Chris and Jordan have some final thoughts.
The EOS R6 II arrives in one of the most competitive parts of the market, facing off against some very capable competition. We think it rises to the challenge.
Above $2500 cameras tend to become increasingly specialized, making it difficult to select a 'best' option. We case our eye over the options costing more than $2500 but less than $4000, to find the best all-rounder.
There are a lot of photo/video cameras that have found a role as B-cameras on professional film productions or even A-cameras for amateur and independent productions. We've combed through the options and selected our two favorite cameras in this class.
What’s the best camera for around $2000? These capable cameras should be solid and well-built, have both the speed and focus to capture fast action and offer professional-level image quality. In this buying guide we’ve rounded up all the current interchangeable lens cameras costing around $2000 and recommended the best.
Family moments are precious and sometimes you want to capture that time spent with loved ones or friends in better quality than your phone can manage. We've selected a group of cameras that are easy to keep with you, and that can adapt to take photos wherever and whenever something memorable happens.
What's the best camera for shooting sports and action? Fast continuous shooting, reliable autofocus and great battery life are just three of the most important factors. In this buying guide we've rounded-up several great cameras for shooting sports and action, and recommended the best.
