Sony making handheld that can play PS5 games makes sense, due to big library of PS4/PS5 games available right from the gate - and if they allow STEAM on it (since MS apparently will), they have very good value proposition for that handheld, especially if they build it around same tech (UDNA) as PS6, which it appears so.
It seems that quality/performance profiles have already become sort of the norm in console space, so having PS6 games have "handheld" profile is really not that of a stretch - if the rumour is true, that handheld is shy of 5TFLOPS in handheld and 6.8TFLOPS in docked mode, but with much better RT performance than PS5, so it's quite feasible for it to be supported and get all PS6 games as well...in the same way that you can currently play PC games on 5090 or 3060 with different level of experience.
Now if they want to go all out, Cerny will make "home" PS6 with sort of a MIG (multi-instanced GPU) in mind - that is (as I already in a way proposed), it will be allowed to multi-instance its GPU (and rest of the resources) and thus provide, in the same console, either "Full" instance (for best experience), "Half" instance (run your PS5 games or 10th gen games with lower settings) and "Quarter" instance (run PS4 games or 10th gen games on even lower settings)...or something like that, depending on how powerful PS6 ends up.
Why this? So they can have first console that can support whole household at once. You and your kids/friends want to play online match of next CoD at your home? Sure, turn on 1 x "Half" + 2x ''Quarter" instances, or 4x "Quarter", and stream it to TV(s) or other preferred devices. Want to play GTA VI by yourself? "Full" profile. Want to play next Horizon while your significant other plays Witcher 4? 2x "Half". And so on.
I know, crazy...but it could be quite a selling point. Personally, I'd expect this more from MS than Sony, given their knowledge of OS and virtualization, but who knows...
