I disagree.

"Please include <common.h> at the beginning of every file"
is a fragile rule.
You have no way to check it.

Our goal is to get rid of the
special treatment of <common.h>

I saw it.

Humans cannot check it.
If buildman does not raise a flag, it is fine.

For the legacy CONFIG options, yes.
The options in Kconfig are all safe.

Common options were mostly moved to Kconfig.

We still have lots in scripts/config_whitelist.txt
but most of them are platform-specific craps.
