I'd be more concerned about pricing and vendor lock-in.
Haven't tried SST though. I doubt if it works always flawlessly because even plain old terraform might get stuck in complicated dependency graphs failing to destroy or create/recreate resources.
I think it depends entirely on the product/audience. The selling points around infrastructure tooling are stability and reliability. Zany marketing like this invokes an "unpredictable" feeling in me which I'm not sure is a good fit.
