You can set the retention globally (whole session) to 1 hour which will actually make it more expensive. The default is 5 minutes.

Claiming that it's more expensive isn't true, it's workload dependent. Filling the cache (worst case) 12 times in an hour is much more expensive than caching it for an hour, and the cheapest is to have your 5m cache refilled by a ping like this is doing.

Imo it's their fault for not having pricing that aligns incentives.
