This sounds reasonable -- I think when we introduced this in 3.6 we were worried that other implementations (e.g. Jython) would have a problem with this, but AFAIK they've reported back that they can do this just fine. So let's just document this as a language guarantee.

Hello, would it be possible to guarantee that dict literals are ordered in v3.7?

The issue is well-known and the workarounds are tedious, example: https://mail.python.org/pipermail/python-ideas/2015- December/037423.html If the feature is guaranteed now, people can rely on it around v3.9.
