Description
In pypa/packaging.python.org#1032 it was resolved that distribution names in wheel filenames should be lowercased per PEP 503, and the binary distribution format spec was updated, but we never began enforcing this.
Similar to #12245, we should warn on upload during a deprecation period before eventually blocking uploads.
Currently usage is very low:
warehouse=> SELECT DATE(time) AS day, COUNT(additional->>'filename') AS file_count
FROM file_events
WHERE additional->>'filename' ~ '[A-Z]'
AND additional->>'filename' LIKE '%.whl'
AND time >= (CURRENT_DATE - INTERVAL '30 days')
GROUP BY day
ORDER BY day DESC;
day | file_count
