To be honest, I feel exactly the same way about it.

I'm unsure why we need *any* 32-bit libraries or binaries on an
amd64 system.  If one needs to run 32-bit software, it is possible to
debootstrap an i386 system and use it as a chroot.  Using a tool such
as schroot handles all of the kernel personality and chroot details,
and even allows normal users to use it with access to all their files,
etc.  With a few one line scripts/shell aliases, it's completely
transparent.  It also has the advantage of being a complete i386
system rather than just a collection of libraries; you can keep it up
to date using the usual tools, and even boot it if you desire.  i.e.
you get all the normal security support and updates.

With multiarch, it's a different story, but we aren't quite there yet.
