Q:

How to apply GAE Application Settings to non-default versions

Is there any way to apply Pending Latency and Idle Instances Application Settings to non-default versions of an application? 
We have both Java and Python versions that must share the datastore/memcache, so we badly want to control these settings for both versions of the app. 
If not possible immediately, any idea when GAE team might add Application Setting support for non-default versions? 

A:

these settings are global for your app and can't be setup differently for other versions than the dafault one. 
can't really answer your second question.  did you try to check out the issue tracker?

you could file a feature request and see what happens
