I would say option #1, publicize POCKET as the predecessor of SMT or, first smart token (not SMT) in steem blockchain. Option #2 may create more complexity and legacy issues since SMT will add more features and upgrades in future. The interface will need to be always updated.

Moreover, POCKET needs to find a NICHE to build a burgeoning community. Right now, it is already used for tipping and contests. Someone proposed to sell whale's vote with POCKET (which is already doable, sell POCKET for BTS, buy WHALESHARES/BEYONDBIT), problem is volume for both POCKET and WHALESHARES is very low. However, it is the early days.

Whatever the option is, it needs a strong niche and use case to stay relevant.
