Oh, you are not the first person asked that :)

And yes, I think this is important that will useful for most developers
and admins. Since the bootconfig already covers kernel and init options,
this can be a new standard way to pass args to kernel boot.

And as I reported above thread, the memory footpoint of view, most code
and working memory are released after boot. Also, as Linus's suggested,
now this feature is enabled only if user gives "bootconfig" on the kernel
command line. So the side effect is minimized.

Thank you,
