Additionally, having the plugin infrastructure gets us the ability to

initify plugin, which can't be done in source alone).

#define __do_const __attribute__((do_const))

#ifndef __do_const
#define __do_const

I think it's always better for the reader to know that a
const struct declaration is used over a non-const struct
when the compiler, via plug-in extension, could convert
the declaration to const.

Is there a warning/info message produced by gcc and the
plug-in when a non-const declaration is converted to
const because of this attribute?
