The docs say, "Version 4.3.1 or higher of the `cx_Oracle`_ Python driver is required, although we recommend version 5.1.3 or later as these versions support Python 3." The advise of "4.3.1 or higher" hasn't changed since 2007 (Django 1.0).
Shai contributed a bug fix for timedelta handling in cx_Oracle which is released in 5.2. Would there be any problem in bumping the required version of cx_Oracle and removing the workaround in Django [0]? I spotted at least a few other workarounds for bugs in cx_Oracle 4.x that could also be removed. As far as I know, the main reason for supporting older versions of other drivers such as psycopg2 is to accommodate developers who want to use their OS packages rather than installing via pip. I'm not sure if there's an analogous situation for cx_Oracle and/or if upgrading presents some other challenges. Our CI server is always using the latest release of cx_Oracle so it's unknown if older versions actually work.
