Comment:

 I found that without sqlite3's
 `DatabaseSchemaEditor.alter_unique_together()`
 `schema.tests.SchemaTests.test_unique_together` failed on SQLite until
 01ec127baec38b7f8281e6eca9def40f22c9e5ad.

 I guess Markus copied the `override_uniques` pattern when he did a similar
 thing for `override_indexes` in d2202ec2d4d0477b682c6d0051f27ab4843ef89f.

 The test added in 03900a02d5fd2efd6ae98bdb9974b78146f63040 fails when
 removing `override_uniques=...` in `sqlite3/schema.py` but starts passing
 after e24e9e0438cf3ba6c557558f68587d135a85e126 so it seems okay to remove
 that instance.
