no becasue it needs also rebuilding because it is a NEW ABI
it is only interesting for embedded devices and means
a third cpu architecture from the view of packages

wyh? because due the changed ABi you need also depending
libraries built for x32

these days there is very little reason to install not x86_64
you can move a linux-installation without big problems
to the next hardware-generation (dd over rsync, move disks...)
and the days of < 4 GB RAm are ending

the better road would be drop i686 completly over the long

the last 4 years not a single i686 package installed
and the world still turns - i686 was yesterday
