Comment (by Adam Chainz):
An alternative to changing the default would be to have a system check
highly recommending READ-COMMITTED, similar to what we do for MySQL's
`sql_mode` (see
https://github.com/django/django/blob/master/django/db/backends/mysql/validation.py#L6
). This would also help educate users a bit more about the change.
Possibly this could be part of a path to changing the default... "Warning:
In Django 2.1 the default tx_isolation will change..."
