To be clear, while the CRSP fast tracked SpaceX’s admission to their total market index, that policy (which states that if a security's total market cap is larger than the breakpoint of the CRSP US Small Cap Index, it is can be added after 5 days of trading) has been in place for at least a decade. Unlike SpaceX’s admission to the Nasdaq, this did not represent a change in policy.
