I don't understand. The patch only affects configuration and SQL data type
code. It doesn't actually store the 64-bit commandid anywhere which would be
the actual hard part.

Do "phantom" command ids mean this all just works magically? Ie, the limit of
2^32 <cmin,cmax> pairs is still there but as long as you don't have to store
more than that many you get to have 2^64 raw ephemeral commandids?
