I understand and disagree. I think you're being overzealous in trying
to bludgeon people into doing things the way you think they should be

From the point of view of the actual update mechanism, what difference
does it make where the microcode data was retrieved from? If you want
to warn about what you consider "unsafe" updates, do that when the
update happens instead. With this patch, simply enabling BLK_DEV_INITRD
will shut up the warning even if an initrd is never actually used.
Also, what do modules have to do with anything?
