The Super Node class supports sidechains. This is a major improvement to the system that moves the project well beyond a simple cryptocurrency. Not only will ZenCash be able to support other platforms over sidechains, but we will also be able to leverage the sidechains to integrate third party technologies.

In addition, required ZenCash for staking is 500 ZEN, which makes it reachable for ZenCash investors.
I think sidechain and its big potential will contribute catching more attention of potential investors and more flows of money into the ZenCash project.
Is side chain supported by super nodes only?
