At least so far. The first go round had the nozzle crash into the tree support, resulting in a layer shift. The good news is that the print stayed very firmly stuck to the bed.
I've reset, lowered my extrusion multiplier a smidge, switched to a more traditional support pattern, and am going for it again. Wish me luck!
None of this stops the risk of fire.
Once a fire starts, the printer turning off won't magically stop the fire from continuing to grow.
Printers can fail in all manner of ways.
Also, you should have a venting solution of printing ASA.
It's pretty cheap to get a proper fire resistant heat cover for a printer.
Just get an emergency "space blanket", they're often only a couple bucks and quite good, but very fire resistant.
