Interesting, I'll give it a shot on my next rig. Looks like it came out after I'd already gotten comfy with Manjaro.
Can't say with my use case I've run into any of those issues, though the cert stuff sounds kinda gnarly, especially to happen more than once.
Unfortunately many North Koreans already leave the country to work as slaves for construction companies, factories, etc (including in Europe). Generally they only allow people out who have families back home to be tortured/killed in case they defect.
They will probably get some, but less than you might expect.
