 *
 * For boolean definitions:
 * - if true: `#define MODULE_[SUBMODULE_]SUPPORT_FEATURE 1`.
 *   (`#define` blank string causes error when checking by `#if x`)
 * - if false: not define anything at all.
 *   (`#ifdef x` is true even when `#define 0` is defined before.)
 *
 * The code depending on this file uses these boolean definitions as `#if x` or `#if !x`.
 * (`#ifdef/ifndef x` is not compatible with `#define x 0`. Though we don't suggest to use `#define
 * x 0`, it's still a risk.)
 *
 * ECO & exceptions:
 * For ECO-ed booleans, `#define x "Not determined"` for them. This will cause error when used by
 * `#if x` and `#if !x`, making these missing definitions more obvious.
