You are specifying the colour of the flowers on the shelf inside
the bikeshed before we've established whether we need to store bikes,
and if we do, whether we need a shed for them, and if we do, whether it
will have a shelf.
If I follow your analogy you're suggesting there's no need to export
VDB. However, there is a need to follow linking both forwards and
backwards. This is generated by portage and cached in NEEDED.ELF.2. On
a PaX enabled kernel, we often have to migrate the PaX flags from
libraries to *all* ELF executables that link against them --- this is
similar to revdep-rebuild.py but for migrating PaX flags. This
information takes ~5 minutes to be generated on a typical desktop
system. However, it is just a *regeneration* of information already
available in NEEDED.ELF.2. Using the latter from VDB takes only seconds
by comparison. It is counterproductive not to make this information
available.
