While there are certainly some packages which may benefit from
compilation with sub-architecture optimisations, those packages are the
exception rather than the norm.

It may make sense to provide multiple versions of the kernel for
example, and perhaps glibc...  but coreutils?  grep?

Do you propose re-building all packages for each sub-arch?  If so,
please consider the resulting increace in archive size and impact on

If only a sub-set, how are you intending to change dpkg, apt and/or the
archive software to handle opportunistic installation of sub-arch
packages with fallback (i.e. try foo.i686, fallback to foo.i386)?
