love the custom admin pages! Works very well for my existing admin pages with just an app.yaml change.
auto-retry is probably for the best now that writes can be easily deferred with task-queue and request latency is not as big of a concern. though I am curious if we can predict how long .get() and .fetch() will potentially block for? Seems like this used to be around 4 seconds in the event of Timeout but I assume it may be longer now.
