I would not say that.
Web services by default do not imply governance.
You can see web services only as technical services. You do not have to 
use a registry when you create a web service. It can work without it.

Governance is part of best practices.
You can apply these best practices to SCA services too.

You can use SCA for your SOA. But that is not mandatory.
You can do SOA without SCA and use SCA without making SOA. There is a 
small space frame for having both at the same time.
