I've posted a new version of PEP 557, it should soon be available at https://www.python.org/dev/peps/pep-0557/.

The only significant changes since the last version are:

• changing the "compare" parameter to be "order", since that more

accurately reflects what it does.

• Having the combination of "eq=False" and "order=True" raise an

exception instead of silently changing eq to True.

There were no other issues raised with the previous version of the PEP.

Not quite; I also raised the issue of isdataclass(ADataClass) returning False. I still think that's likely to be a cause of bug reports if left as-is.
