Yes, without that "zero benefit".  prelink has provable startup performance
improvement and runtime memory savings.

This is repeating argument again and again, there are many benchmarks of
prelink if you have spent several seconds Googling them, one of them even here:

ELF is designed to be relocated, as you can read from the ELF standard.
And prelink is even designed to very easily provide the original binary form.

The problem is battery drain, everyone tries to optimize battery drain
nowadays, to be "green" and to extend portable devices lifetime.
prelink contributes to the battery drain solution.

Unless you can claim we should compile everything with -O0.
