Proper Idle Time???

Here is an interesting link I found on synthetic vs mineral oils What are Synthetic Oils? | Types of Engine Oils a little off topic but still adds weight to your point AVC

You do need to idle for some period of time to let tractor to cool off. Idling for extended periods of time like we used to do in the past is bad for anything with DPF or is after cooled. Can bring to 1,000 RPMs and leave all day and not issue. The fire trucks and ambulances with DPF that idle for extended periods have been having all kinds of issues. That is my experience on trucks anyway. Can't imagine tractors will be that different.

I believe the ems vehicles got an exemption from dpf requirements because there were so many issues.

Not in the state of Illinois anyway.

Sounds to me like all these issues are due to bad "software programing".
Whoever is setting up the parameters for this is way off base. I don't see why a machine would have to "Stop" for a regen if it's not done in time, sort of a hazard in itself.
There definitely should be a "bypass" for this included, and some sort of warning that a regen is needed but the sky isn't going to fall if its not done immediately.
These little tractors should be exempt from all of this, maybe a catalytic converter like our cars have,
when they plug up, a light comes on and "You" change it, thats it.

My first regen came at 20 hrs. I was burning a tree pile and the light came on, I ran the RPM up till one light went out (2500 rpm) and push a button. I didn't quit working, just keep the fire under control as I added to it, and 10 minutes later the rest of the lights went out. I now have 37 hours on the tractor and am anxious to see if it calls for it again at 40 or so hrs.

It was direct from the EPA:

the item shown is a proposal. Was it enacted?

If you must get off the tractor for a period of time, say less than 5 minutes then set your throttle to about 1200rpms and do what you need to do. That will keep the the engine warm enough to keep your regens down. At idle the engine begins to cool off and more particulates pass to the exhaust. The computer reads this and will regen more.

I shut my tractor and my diesel car down if they have to idle more than about 20 seconds. Safer to get off your tractor with it shut off (brake on, etc.).

They'll soon have diesel hybrids that'll be shut down and restarted quite frequently, like a Prius is.

I've only ever had to replace ONE starter on any vehicle I've ever owned. Don't think you're likely to wear the starter out.
