One solution to that problem is to have someone who maintains a separate
tree for uboot which does have the feature in.  Then it becomes a matter
of community choice whether they use the official tree or the tree with
sensible machine-id configurability.

That way, those who want the configurability can have it, and Wolfgang can
avoid having his tree polluted with useful features he doesn't want.
