'Rolling out of new AWS services and features
Quite often when new AWS services and features are released only in some of the regions and not globally. Is there any reason for it? If it's a new EC2 instance type requiring a new hardware then I can understand rolling in a few regions, but even the small software related features are rolled out incrementally.
For ex., the recent announcement of the CloudFormation Stack Termination Protection has been rolled out in 14 regions out of the total 16 regions. It makes it quite difficult with so many services to follow where a particular service and feature is rolled out and not.

14 of 16 is effectively everywhere -- the China and GovCloud regions are not accessible from normal AWS accounts. So, that is a worldwide roll-out.
However, you are correct -- often new services are released in only a few regions (typically N.Virginia and Ireland) with global expansion later.

AWS will release most of it's new features in N.Virginia(us-east-1). After the maturity and success the feature will be implemented in other regions. Why N.Virginia(us-east-1)? For AWS this is the first-most region almost all services are available and having 5 Availability Zones.
