This is an interesting approach especially if you factor in that re-minting a key is usually a lightweight task compared to what most API calls have to interact with.
If the re-minting happens transparently with a user interaction then you spread out some of the request velocity that can come with that (if you're operating at a large enough scale for it to matter for this to be a concern).
