Why use a Raspberry Pi with a Duet 3?

If this is important, I think the real answer is to implement a call from RRF to the Pi to get the list of files in a folder, so that RRF can implement M20. I don't think it should be hard. If M36 was implemented in the same way then it would also be possible to start print jobs from PanelDue.
I just would like to add my positive vote for this. It would give much more flexibility in setting up duet 3 boards.
While it's possible to run both HDMI and USB cables to a small screen, the simple fact is that the wiring for the PanelDue is much smaller. There's also the fact that the PanelDue UI is a mature, well designed, simple small screen touch interface that's proven.

@garyd9 apparently one of these tiny chinese hands which are capable of handling smallest screws at hidden places.

Perhaps I'm over-simplifying, but...
Is it correct that the PanelDue just uses serial communication with the duet board? Is it also correct that the PanelDue just uses gcode commands and responses to display data and take actions (in a manner very similar to how DWC works)?
If so, would it be possible to just connect the PanelDue directly to the SBC and add serial code support to the daemon on the SBC?
"I'm not saying that you are wrong - I'm just trying to fit it into my real world simulated experience."

Yes. But we plan to change RRF to send file-related commands received locally by the Duet to the Pi anyway.

No need to add anything. Search forum for socat

I've been trying to justify using rPi with Duet3 myself, and its not the cost :-). If you want wifi, you can always use a router in bridge mode and plug Duet3 into it.
Using rPi I see as have a few concerns: It's adds another possible point of failure. Maybe needing additional cooling, not to mention the extra space needed in the box for the board. What about power? rPi is a computer and should be shutdown properly. If you turn the power supply off you also cut power to rPi, or you have it setup another separate power supply to keep it running. Or you have to do a lot of rigging to have the rPi shut down properly then shutting off the noisy power supply.
It's nice that it's easier to update the system. If you have a spare rPi laying around doing nothing, then maybe or you want to experiment. You can always add one later on down the road. I don't foresee anything coming down the pike, as a plugin, for a long time. So far I haven't even seen anyone with a great idea for a plugin and I can't think of any except maybe display the model that's in the stl file(s). -
In the near term it offers greater choice in touch screen interfaces and easier customization of the touch interaface compared to the PanelDue.

I'm using an iPad and I can walk away from the printer and still have control
. PanelDue I manly use to home or to remove filament, which I could do on the iPad too, just a matter of convenience. -

Unless your telling me it has a better and more information on the web interface on the rPi then it does on the duet3 -

But for printer manufacturerse etc that want to customzie things the rPi makes it easier.
Using an iPad has all the downsides of the rPi at a greater cost less the customization options. But again, if it servers your needs, then you're all good.

edit: actually some users have been rather keen to adopt using Rapsberry Pi with existing Duet 2 to improve the upload speed, and my limited testing shows a significant difference. Unsure how Duet3 stand alone uploads compare as i never tired but I recon there is yet room for improvement.

ive been running my duet 3 in standalone so far , i have a extra rooter so my duet has it own lan network that i can access via my PC or my phone when him at home , thinking in the future to maybe use a cheap tablet for it as well ,
