OK – of course you're right that those workarounds can easily be added later.
As long as you've thought about this and checked it, I'm happy.
(Now I've slept on it, I think I vaguely recall that one rationale for
armlink's choice of behavior is that it makes partial linking change the
semantics less: if you combine a bunch of `.o` files into one big `.o`, then
passing the combined file to a full link step has a very similar effect to
passing the individual files one by one.)
