I think the warnings are useful, it's just that they're not important
for all structs.  If the struct was getting allocated a lot it could be
pointing out an issue that makes a real difference.  I'm not sure it s
realistic for automation to figure it out for itself so it's better to
send them even if they get ignored a lot.
