They won't be signed.  Authentcode key signing is structured

Couldn't agree more, a moronic design if you asked me.

The Symantec code signing service, however, ties a distinct key
to each signed object in an auditable method.

As Rob is fond of pointing out, there are literally hundreds of
moving parts in their release (and similarly in the httpd release
as well - each loadable module must be signed).  I've asked and
been assured that the Symantec service would have a batch/group
automation-friendly submission process that could make this
relatively painless.

When I scoped the first ASF-hosted service, I envisioned then
editing each .rc resource entity in the binaries to associate
them to the pgp key which had submitted them for signing, before
then authenticode-signing the objects.  But this still suffers 
from exactly the threat you identified above.
