> But `LogTemplate.created_at` has `default=timezone.utcnow`, which should
kick in to add a default value on the client side to the insert query,
[according to
documentation](https://docs.sqlalchemy.org/en/20/core/defaults.html). This has
been working fine in 1.x and I don’t see any notes indicating anything changed
