The `complement` method of vector subspaces is being renamed to `orthogonal_complement` (with deprecation) in PR #39659. This is because the method returns the orthogonal complement (which is not always a complementary subspace). A genuine complementary subspace can now be obtained by calling `complement(orthogonal=False)`, and that will presumably become the default for this method after the deprecation period.
