High profile deprecations are handled carefully and we usually handle them with extended deprecation period with clear migration path/doc and communications. Notable examples in the table:
1. Python 2.5: 4+ years
2. Java 6: 20 months with existing user automigrate to Java 7
3. Java 7: 13 months with existing user automigrate to Java 8
4. Master/slave datastore: 3+ years.
Considering App Engine is the first Google Cloud offering, I'd say we have a very good track record of meet our deprecation policy and usually exceeds it.
