I guess it would break things on some machines if the module loading
order isn't setup properly.  For example, it's known that
pinctrl-cherrytrail breaks MMC or others if it's loaded too lately.
On distros, we often work around it by a specific module loading order
in initrd.

But this doesn't mean that the modularization itself is wrong.  It's
merely a setup issue.
