This assumes that you have a single source for the fix delivery.

In the OS/App differentiation, you are expecting each is coming from a
different source.
Apps are either boxed, or coming from a project.
The app provider should fix their version of libxml, and the OS provider
should fix their version of libxml.

Are there periods of vulnerability? Yes.

Now, if the OS and the Apps come from the same source, example - Fedora,
could Fedora Project do something innovative such that the fix to the OS
and App arrive almost simultaneously?
Possibly - but requires rethinking the build workflow to enable
multi-target capability and a better understanding of how different
languages and applications have hidden PATH assumptions.

Is Fedora capable of innovating on this level? I think so. There are a lot
of smart folks here.
