In summation no one else has an over heating WAP
More likely nobody else checked or they assumed it was normal, which it probably is.
I would be curious to know if they checked others of the same model to see if they do the same.
Its not impossible its faulty, but I'd still argue its unlikely to be a fire risk as if it got that hot it would melt something on the PCB and die at much lower temperatures than a halogen light bulb reaches, all happening isolated in the case which is likely self extinguishing to avoid fire.
On average, a halogen bulb can reach temperatures of around 250 to 500 degrees Celsius during normal operation. This level of heat can be significant, especially considering that traditional incandescent bulbs typically reach temperatures of around 150 to 200 degrees Celsius
A voltage regulator for example will either fry or shut off at around 135C. Other components would fail at even lower temperatures.
A device will start to feel "too hot to the touch" at around 40C by comparison, and feel "alarmingly hot" at 50C. Yet a lot of laptops will run their CPU at 95C, my gaming laptop by this measure will get "alarmingly hot" under heavy use as even with the fans flat out the surface temperature gets too hot to touch.
As I understand it the legal requirement is that its not allowed to get so hot you will burn your finger before you have a chance to remove it, but things being mounted to a ceiling do not necessarily have this requirement as you're not supposed to touch them in operation.
