I've seen more than a few people in the CT groups that have done exactly this after actually test driving a Tesla.Tesla (TSLA) turns to Cybertruck reservation holders in delivery push
Makes sense to try to convert Cybertruck reservation holders to customers earlier.
TL;dr Cybertruck is still at least 1 year a way. Tesla is trying to get reservation holders into S3XY in the meantime to increase sales in the meantime.
