There are many reasons why a mixed system might be required. Each of
them will only apply to a few % of users. To name a few:
- binary only software
- 32/64 bit only software
- programms that need lots of memory that exceed real memory in 64bit
- programms that need lots of memory that exceed the 4G boundary in 32bit
- programms that overall run vastly slower/faster in 32/64 bit
When you have a system where a 32 bit _and_ 64 bit rule applies
multiarch would be beneficial.

Not easy to install and maintain. Even the properly buildd systems end
up with daemons left running or replacing the real ones in the chroot
and similar problems. Debian has no way to setup a full chroot that
won't interfere with the real system or where one can decide what runs
where. Its all manual work.
That doesn't mean there won't be one and something to better control a
chroot would be benefitial to the buildds and every chroot user as well.

Needs a reboot. Blasphemy. :)
