Not relevant to what you are discussing related to attention to detail (which I agree with).

This is my imaginary scenario -- if Steve Jobs were to tell me in a meeting, "I see air bubbles coming out of the phone", I (as an engineer) would reply to him, "Dude, that air is carrying excess heat out of the phone via convection. If you don't leave any space in between hot electronic components, your phone will be a toaster or a clothes iron".

It's fine to explain why it is the way it is, but at the end of the day that's still just an engineering problem you need to try and solve. Sometimes Apple made mis-steps in that size/heat scenario but they've done it a hell of a lot better than anyone else for a long time. Sometimes you need demanding product types to force you to put serious effort into an engineering challenge you don't deem worthwhile.

There aren't a lot of phones that have air vents, except for the ones that also have fans. Convection doesn't work at those sizes and power levels. Thermal design for phones is all about conduction, getting the heat out to the surface of the device and spread evenly enough that there's no hotspot that would be uncomfortable for the user holding the device.

Some phones have fans??

There are phones made specifically for gaming, and some of them have fans.

In an alternate world where your phone has a Core i7

No idea, but technically some phones are now water-cooled.

I have seen reviews of redmagic and asus gaming phones with fans.
