We use PropelBundle and Propel1, and are trying to keep up with Symfony LTS. Since Propel2 is still in alpha, we made updates to PropelBundle to allow for Symfony 4 with Propel1.
This really ought to be against a "1.7" branch, but there isn't one in the upstream project.
All propel 2 dev should go into https://github.com/SkyFoxvn/PropelBundle as this will most likely be the follower of this now.
But 1.x issues could still be released here.
