Why would you include a flat like that in the mix? Whether tubed or tubeless a tube would be required for a puncture like that for roadside repair.
The whole point of tubeless is sealing up the types of punctures that normally would require you to have to pull the wheel and change/patch the tube. Putting a tube in a tubeless tire is not messy nor a hassle.
As I mentioned earlier...you don't know what you don't know.
