SuperTestnet explores cool stuff. Not sure how this is an oxymoron, but I do see it as a bit convoluted. If one has a way of transferring a private key conveniently, one might just delegate the ownership of an UTXO. Maybe the Ark way is more cost efficient and flexible, as long as the ASP cooperates.

This is an oxymoron thing. But I appreciate all the experiments SuperTestnet is doing.
