Here is what I got out of this thread so far.
1. You can have your bike idle low be it EFI or Carb.
2. Low idle causes low oil flow to the heads.
3. Carb bikes had the luxury of a choke that you could up the idle with a turn of a **** or lift of a lever. EFI doesn't, and with this could come issues with oil flow to the heads. Although you have a throttle so I guess you could up the idle by holding the throttle or setting the throttle lock.
4. you might have charging issues if you idle for a long period of time
5. F#!k it and ride. If you wanna idle low/idle low. There are hazards that could arise, but its your bike. who is to tell you what you can and can't do with it.
:::EDIT:::
There is something about a loping bike, but I am not willing to risk the damage at this time. I know my BIL's S&S 110 runs at 12 lbs on his oil gauge when his bike is completely warm. What is the oil pressure on a Harley with the 1000-1050 RPM idle?

I still think the carbed bikes have more lope for two reasons and idle speed isn't one of them. Lobe separation and less efficient fuel delivery at idle. I put Andrews 26H cams in mine and it lopes a bit more than stock because it's not designed for the EPA. The carbs rely on air flow to feed the engine and at idle signal is not that good creating the lope. EFI relies on sensors and maps to deliver the fuel, that coupled with no overlap equals a relatively smooth idle. You want lope with out damage get cams, simple enough.

Avoid the guess work and install a decent oil pressure gauge. And not a crap Drag Specialties gauge, but one built specifically for our bikes. One that can actually read just a few lbs. I can say from experiance, my Shovels and Evo's make very little oil pressure once they are hot. Not warmed up per-say, but hot. At those times I would not want a 650 idle. I have one of these on my bike. Nice part if I do say so myself, and removes any doubt about pressure.

My 2010 bike has what I'd call a subtle stutter on idle (every now and then skips a beat). I asked the guy at the dealer if that was normal, and he said the MoCo programs that into the ECM so it can approximate carbed. I'm not sure if I believe that - you?

Don't know, but my lawn mower has a carb, and it doesn't stutter. Well when I run over rocks and stumps it does.
This has been cool, and the LC1 Wide band doodads looks pretty cool, but if you have a SE Super Tuner can't you just tune it down to 14.1 or 13.8? Why would you need wide band O2?

How did your question relate to idling? The issue isn't the bike going lean, it's a lack of oil pressure.
