Pulp

Currently Pulp 3.0 is compatible with Django>=1.8.
The initial idea was to release Pulp 3.0 with the latest Django LTS release available which will be 1.11, this is also the latest release in 1.x line.
At the same time Django 1.8 LTS will be supported until at least April 2018 so some users may still want to use this LTS release.

Pulp 3.0 is not expected to be included in Fedora 25 or 26 and also Django 1.11 is not available there at the moment.
Though we may want to distribute Pulp 3.0 on our own for Fedora 25 or 26 and in case of Django 1.11 requirement, python-django package should be distributed by us as well.
As for the supported RHEL distributions, only Django 1.11 will be available in SCL.

The task here is to decide closer to Pulp 3.0 RC release whether to require Django 1.11 right away or drop Django 1.8 support later in case Pulp 3.0 will still be compatible with Django 1.8 by that time.
