Which functionality will I lose by placing /tmp on the real disk?

Right, system will become unusable and user will press Reset button far
before that.

Since we're talking about default settings, you assume default debian
system to have at least 2.5GB just to be able to unpack kernels?

I don't understand your point. I could understand it if we were choosing
among benefits that most users get from /tmp being on disk and /tmp being
on tmpfs. But there're NO benefits in having /tmp on tmpfs. It works (not
works better, just works somehow) only on systems with a lot of RAM. And
nobody still named any popular programs, that can definitely benefit from
that. While there're many programs that either break or may render system

Yes, /tmp on tmpfs works in many cases. But /tmp on disk works always.
Why would we select the worst of these two options?

I don't understand, do you suggest to break some applications and make
system less stable for nothing? What's a good part?
