Okay, we agree that this default makes more sense. But I think the name `conly` does not make sense if it defaults to `True`. Instead, lets rename to `enable_cxx` and...

I don't agree with your diagnosis of `cffi` silently breaking due to kwargs. Its passing the kwargs to something that doesn't accept the `conly` parameter as far as I can...

We have an internal "example repository" that we use to validate that the open source equivalent of our build rules will continue to work. I got approvement from legal team...

Pants doesn't support a hermetically source built python so I'm not sure I would say it supports it natively. Its support is more similar to bazel upstream than these rules...

I think it would make more sense for this list to go in cfg.py, or disable this feature altogether in the open source version of our build tools

Actually, I think it makes sense to remove this list entirely, and add a flag to piplib `preserve_docstrings` that defaults `False`.

Our mypy rules don't seem like they actually function here, and its not caught in our internal smoketest since it doesn't include any references to `dbx_mypy_test`. I'm not sure what...

`# type: ignore[mypy:misc, other_checker:foo]` seems like a better syntax and actually compatible with the parser. In the case of mypy we would simply recognize `mypy:x` as the same as `x`...

Given that there is not a standardized behavior for these in the PEP I don't think we should be restricted by what choices Pyright makes. It would be a simple...
