Why not?  If you don't get a warning for the attribute being
ignored then, your target doesn't really pack structures; maybe
we need to split default_packed into variants.

Uh, no.  It works as intended and removing it would cause a
regression.

On the other hand, FWIW, I think the warning is generally bogus,
but I've already mentioned that.
