For me, it is also hard to judge, so at present, we can assume it is not
worthy enough for other individual modules.

Yeah, so our 'goal' is OK, but we need focus on 'how'.

At present, firstly need modify 'init/Kconfig', and then scan all
architectures one by one, let each related patch pass checking by the
related maintainers (which can avoid the risk).
