Google App Engine for WordPress app.yaml

I know its not directly related to this plugin but would anyone have a working app.yaml for the latest version of GAE as the developer version here https://developers.google.com/appengine/articles/wordpress and the github version here https://github.com/GoogleCloudPlatform/appengine-php-wordpress-starter-project/blob/master/app.yaml don’t work with the version of GAE at the moment.

If you use the handler values defined at the time of writing you get an error when you use appcfg.py to update your code on GAE

Error 400: — begin server output —
