It is already possible to select a couple of “plugins”, see smart contracts. I suggest that a marketplace is created where verified audited smart contracts become available for the economies/communities.
A possible prerequisite in order to make any of them available, may be an audit by a respected auditor with all issues addressed.
In addition, perhaps it should be clearer how may an economy/ or community administrator enable his own smart contracts with a notice in case it is not audited.
