I think you misunderstand.
The lib (app) is about properly _creating_ the partition with
all magic. So basically every formating tool should zero out
parts of the partition and _then_ write the new magic there.
Obviously some tools fail to zero out the space. This is what needs
fixing.
Pushing the problem to kernel-space, by implementing a faulty-by-design
scoring system is IMHO not the way to go.

BTW:
I often saw this problem in the past, especially with swap and fat
related partitions. So I now always use dd to zero out the first
part of a partition before I reformat it.
That's a good workaround the broken format utilities.

To summerize: I don't think there is something broken in the kernel,
so I don't think we should go and fix nonbroken code. Fix the
broken code in userspace instead.
