Pretending things don't exist is kinda a how Steemit Inc roles, and asking stuff like this? Think you just stopped existing yourself for Steemit Inc, asking this ;-)
Steem-Engine tokens vs SMT will be pretty relevant after HF21 hits us. Especialy if (what would seem a quite logical thing to happen) HF21 ends up pushing much of the current minnow/dolphin stake to scot tribes, its not unlikely that HF21 will end up making SMT obsolete before HF22 has a chance to solidify.
Native blockchain tokens won't be obsolete. While both can possibly coexist, there are a lot of reasons for new projects as well as existing tribes to use SMT. I wrote a post about it a while ago.
LOL... Very good points. And no comment from the steemit inc team how surprising...
