This is an electronics housing printed in Innofill FR PLA, and this is what happens after a few years. Note that this is with a heat load of just 4W!

It spontaneously disintegrates. It makes you rethink on the use of PLA in certain applications, flame retardant or not...
Trying PETG-V0
After looking around for FR materials, I picked up Fiberlogy's PETG-V0 and tested it. And I can confrim their PETG-V0 does NOT burn and is fully self extinguishing.
I updated the model with some larger ventilation holes, and printed it in PETG-V0. I just have some troubles with what I suspect are retraction related, though I'm not sure. I see these sections where it looks like the material didn't 'start' properly, but this only seems to happen on seems in the middle of rather large, flat sections. Another thing to figure out...
I have two materials available if I can't get PETG-V0 to work properly, and that's eSun eABS Max and Filament PM's PC-ABS, but I guess I'll install the PETG-V0 variants for now until I've figured out my best option.
