Per the SQLAlchemy docs [1]:
The relationship.backref keyword should be considered legacy, and use
of relationship.back_populates with explicit relationship() constructs
should be preferred.
A number of the relationships defined here don't have foreign keys (long
live mordred?) so their conversion is slightly more difficult than would
otherwise be the case. A blog post is available to explain what's going
on [2] and might be worth a read. The learnings from that blog post do
have the benefit of allowing us to simplify some existing relationships
that had unnecessary arguments defined.
