If user is clever enough to reflash a phone she will find the strings
easy especially that they are provided from: (i) bootloader which is
even less likely to be reflashed and if someone do reflash bootloader
she is a guru who'd know how to make the strings; or (ii) platform
defaults which will be available with the rest of the source code
for the platform.

Imagine a developer who needs to recompile the kernel and reflash the
device each time she wants to change the configuration...  Command line
arguments seems a better option for development.

And the configuration is needed because it is platform-dependent
so it needs to be set for each platform.
