no one is looking into the SMTs.

Probably because it is not easy to understand the code, the idea and the financial interdependencies. A lot has to come together to finalise this effectively. But are there only two people in the world who can do that?

I will dig more into token creation without SMTs or side-chain strategy.

Right! Having multiple approaches is good.
I will follow this with interest and perhaps I can contribute a little... and I've seen that remlaps has put together some interesting older facts that might help.
