I don't think it is possible to standardize stats ids, for two reasons: - it is hard to maintain and avoid conflicts between drivers - the drivers would have to lookup the names which degrades performance I think the idea of Olivier would improve the performance of stats retrieval, which was the idea of this rework :) Unfortunately we need someone available to fix it quickly for RC2.
