Such functions are never used after MicroPython has started, and they remain in RAM wasting space. Now they are placed in a special section named "boot" which sits just before the heap, allowing us to extend the effective heap area up to the new boot section. Right now, this gives us back ~1K, but in the future, more functions might end up in there as well.
