Tech Report: Include semi-step CrUX ranks
Starting in 202210, the CrUX dataset includes semi-step ranks: 50k, 500k, 5M, and 50M. These are in addition to the full-step ranks that the CWV TR currently supports: 10k, 100k, 1M, 10M, 100M.
Consider adding support for the semi-steps.
Need to be careful not to create confusion with this feature. For example, in 202201, there is no 50k rank, so the current implementation of "rank <= 50k" would only include the top 10k despite being labeled as "Top 50k". Maybe that's tolerable, or maybe we should find a way to make the semi-steps available only after 202210.
Closing this as not-planned. Npot sure how useful it is and the complications regarding the old data adds further complexity.
