Research direction

Start by locating the environment-marker validation and parsing entry points in setuptools; the issue names platform_python_implementation and implementation_name as the unsupported markers. Compare the accepted markers with PEP-426, then confirm completion when both markers are accepted without an "Invalid environment marker" error and are covered by tests.
