I could challenge you to create a setup to prove the significance of this: A compilation that would consistently take noticeably (more than 1%) longer compilation time with an "uber include" than with individual includes for what you really need

Easy Peasy:
Shell
[k5054@localhost]$ cat ex1.cpp
#include <iostream>

int main()
{
    std::cout << "Hello World\n";
}
[k5054@localhost]$ time g++ ex1.cpp

real    0m0.208s
user    0m0.148s
sys     0m0.058s
[k5054@localhost]$ cat ex2.cpp
#include <bits/stdc++.h>

int main()
{
    std::cout << "Hello World\n";
}
[k5054@localhost]$ time g++ ex2.cpp

real    0m0.865s
user    0m0.718s
sys     0m0.142s
[k5054@localhost]$ 

That's a 400% slow down. I've never done that in real life. I stumbled across bits/stdc++.h only a couple of years ago, I think in QA. Not sure why the GNU maintainers allowed it. It seems like a good way to get a whole raft of unexpected results.
