No, shifty isn't the right word. Without knowing what App/Service is above consent and what that App/Service does, I'm reluctant to label their actions because the Notification is correctly showing something accessing Location Services and Apple admitted it's happening.
It could be something innocuous and dumb like the Location Services service periodically caches GPS Ephemeris data, and since it's accessing itself to pull that data, a notification pops up.
It could also be something like the GovernmentMandatedTracking Service periodically querying your location.
The first example isn't shifty, it's just kinda dumb. The second example could be seen as either kind of like a Warrant Canary or incompetent if unintentional. Given the fact that Apple acknowledge it, I would lean towards Warrant Canary.
