Do we have preference?  I think it is more common in our codebase to
have these non-static but I do not think we've chosen which is more
preferable with technical reasoning behind it.  As the top-level
function in any callchain, cmd_foo() does not have multiple instances
running at the same time, or it does not have to be prepared to be
called twice, so they can afford to be static, but is there any upside
for them to be static?

Okay, so that's one upside, albeit a small one.
