Comment 66 for bug 1314129

@Carl, yes, latest simplejson gets new features that should eventually arrive into stdlib json module once another sync is done. We should handle any significant differences that results in unexpected discrepancies as we do when supporting multiple Python versions. For this specific case, if we really need to retain the old behaviour of stdlib json module, and we target simplejson > 2.2, we could enforce it via namedtuple_as_object set to True. Though I would make such modifications only if real issues arise.

Answering to your question ('How many types were tested for equivalence?'), none of them specifically. Tempest runs and tests in the lab were used to ensure no regressions are introduced.
