comment EC2 drive not EBS volume size
I would recommend petitioning centos.org to stop building AMIs with partitioned root EBS volumes. There is no benefit to this if you're using a single partition and it makes resizing more difficult. Amazon doesn't do this with their AMIs. Nor do Ubuntu, Red Hat, and others. It's a best practice to simply lay the file system on the raw EBS volume without extra useless barriers that need to be moved around on resize.

Who published the CentOS AMIs you used?

comment EC2 drive not EBS volume size
Extending the partition is only necessary if the volume is partitioned. That is pretty rare on EC2. The common best practice with EBS is to format the entire raw volume with the file system without positioning it first. This is especially true for boot volumes. Positioning is an artifact of physical disks, where they aren't quite the size you want for your file systems. On EC2, you simply create EBS volume(s) of the right size and drop the file system on the raw volume without partitions.

comment The instance created from EBS snapshot fails to launch
@martijnheemels I think most PV AMIs have been using the same PV AKI. Yes, snapshots can have tags, and ec2-consistent-snapshot can add tags, but why not register snapshot as an AMI at create time? Shouldn't add any cost over the snapshot itself.

comment Auto-terminate EC2 instance when image is created
@AlexB Good catch. You could include a test that only halts if the instance id is the id of the current instance.
