The aluminium chassis cannot be used for heat dissipation without risk of harming users. Which is why there is a "macbook air peformance mod" to add thermal-interface-material (instead of thermal insulation) to turn the chassis into a heatsink.
The last generation of Intel Macbooks was so bad... the i9 I was assigned from my job at the time would constantly go in and out of thermal throttling, making the whole experience effectively useless... It was also so locked down, I couldn't apply any mods to be able to underclock/volt the thing to something reasonable.
I really do hope that Linux becomes an option in more workplaces without being too locked down for developers.
I believe we are talking about slightly different things. Yes if they thermally coupled the body to the processor, then a small patch of the body would get very hot, burning the user.
However, the fact that the aluminum gets hot during prolonged use means that it is acting as a heat sink and cooling the CPU compared to a body made of plastic. Thermodynamics, it's the law!

Not really. It's picking up "stray heat" that is radiated from the copper heatsink inside and conduction from the air in the fan system. It does not improve cooling the processor in any kind of manner. If it were plastic, the plastic would get warm too. Maybe it'll be a 2 degree difference.
