Research direction
Start by reading PEP 557 and comparing its dataclasses and fields interfaces with attrs' field and attr.ib APIs. Define the intended namespace and document the incompatibilities and adapter scope before proposing an implementation. Done means the migration and compatibility behavior are specified clearly enough to review.

Description
Extracted from https://github.com/python-attrs/attrs/issues/408#issuecomment-514375369
On the other side of this, what about making a namespace that actually is intentionally similar to PEP 557
dataclassesandfields, and just has a thin adapter layer betweenfieldandattr.ib, etc? How much incompatibility is there beyond the names? Isn'tattrsmostly a superset?
It would be good for migrating from large codebases where dataclasses are already used, or for pythonistas who want codebases/apis that stick close to the PEP specifications where possible.
