Apart from source-based alternative distribution for Debian, "bumping
amd64
baseline for selected packages" is another project I proposed long

Software like Eigen3, TensorFlow can heavily benefit from the baseline
bump.
At that time PyTorch did not have dispatch, but now it has already.

You probably already know this, but Ubuntu is exploring the possibility
of an x86-64-v3 variant [1][2]. That would include AVX2, FMA, and F16C instructions (among others), essentially setting Intel Haswell (2013)
and AMD Excavator (2011) as the baseline.

Sincerely,
Cory Bloor
