There are reasons to be alarmed at the "throw stuff at the wall and see what sticks" approach.

Like perhaps you decide to use a product that they're not particularly interested in supporting very well, and a year later they decide to shutter the service which performs a crucial role in your environment...

I am not suggesting that Amazon is actually going to do this, but it's certainly more likely than, say, EC2 going away.

AWS has sunset features before (SimpleDB for example) but only for new customers. Old customers that use the EOL features 1. get a migration path 2. keep the features in their account.

Aside from SimpleDB which was replaced by DynamoDB and Elasticache I'm not aware of any withdrawn services in AWS' history

Elasticache is still there, and it is still getting updates and new features: Redis got bumped to 3.2 a few months ago, and they also added managed sharding support.
