There are tradeoffs, as everything that tries to scale Bitcoin and yes and I know them. But it has unilateral exit: 
Unilateral Exit - Spark
You can keep repeating that but #Spark does NOT have unilateral exit. Governments or government agencies or operator can freeze Spark funds until KYC is provided.
The Spark operator is also able to steal funds, so it's not trustless either.
Spark is a corruption of Ark.
