A governance proposal was needed before the introduction of [Partial Set Security](../features/partial-set-security.md) (PSS) because validators were required to validate a consumer chain. However, after the introduction of PSS, a consumer chain can be either _Top N_ or _Opt In_. If a chain is an Opt In chain, then no validator is required to validate this chain unless they choose to.
