The RF 600/800 will be perfectly fine on the R6. On the R you may spot some softness. More so on the R5. So it all depends.
The RF 600/800 are not targeting high-end users anyway. These are just "affordable" (non-L) options - surely meant to lure away users from APS-C/MFT.
Most will also use these lenses without a tripod at ISO 800+ and combined with air diffusion diffraction may be the least of your issues then.
This is also a lesson from the Leica 100-400mm. At 400mm f/6.3 (aka 800mm f/12.6) you are already beyond the verge of what can be used handheld in an "enjoyable" way.
I wouldn't really recommend the RF 800mm unless you already know what you are up to (and the RF 600 is also attractive due to its more efficient IS).
