That case would easily covered by multiarch and partial architectures.
There would be a i686 arch with just the optimized packages and apt/dpkg
would allow that arch if the cpu supports it. The configuration doesn't
even have to be in apt/dpkg but there could be a arch-detect package
that contains the detection logic and outputs suitable config for
apt/dpkg.
This would also solve the problem of having to use wrapper scripts,
diversions or runtime detection in binaries to provide an optimized
version.
