SWR keys in the sidebar. mutate() is checked against useSWR, useSWRImmutable, and useSWRMutation.
The match is exact. mutate("/api/user") does not match useSWR(["/api/user", page]), because SWR treats a string and an array as different keys. A key built from a variable is listed, and it is not compared.
A useSWR key that nothing mutates is normal, so it is not a warning.
What you get
Sidebar of cache keys
Jump from mutate() to the matching hook
Warning when mutate() has no matching key
The sidebar stays empty until the workspace depends on swr.
