Note that a large fraction of that will be CI systems that get default
Ubuntu pip (18.1 mostly), and could be very easily updated just like we do
in our own CI (a simple `pip install -U pip`).

If you really want to get to a small percentage of pip <19.1, we can wait
for another 5 years. Which seems undesirable. While I agree that we can
keep manylinux1 around for a little longer (maybe another year or so?),
gating it on Linux distro pip version defaults would be odd. Pip is still
very immature; people with a several years old Pip would be well-served by
having to upgrade it.

Cheers,
Ralf
