I think it may still be too early to discontinue manylinux1, sadly.

Systems requiring manylinux1 are those with:

pip < 19.0 (Jan 2019) [1]
Linux distribution older than around 2010 (glibc < 2.12) [2]

I did a PyPI BigQuery [3] just now, editing to give results for 32,
and 64 bit (by changing the manylinux wheel name matching regexp).

Then I processed a bit with Pandas [4].

It looks like about 34% of PyPI manylinux*_i686 downloads are for
systems that actually need manylinux1, and about 17% of
manylinux*_x86_64.  See the table in [4] for a listing of the top 10
entries.

Cheers,

Matthew
