Disagree, because I've got a hand full of these from different brands in operation right now. One even from the major CPE-equipment manufacturer in Germany. I know because they looked 'fishy' to me when they arrived, and I researched into that.
I opend some of them non-destructively to check them out, and deemed them sufficient. They barely get warm at all.
Nonetheless I put them in some closed rack where they only could produce some stink, but no fire.
I'm too lazy to unplug them right now to upload photos to Imgur, or such, because it would disrupt some services.
Anyways, no urban legend. Just the usual bureaucratic disconnect from reality, saying otherwise.
Meanwhile another bureaucratic entity, the german customs really likes to hassle you because of exactly that sh..! :-)
edit: Some of them in continous operation for just over a decade, some others about 5 to 6 years, YMMV. (shrug)
