Indeed. There's even a name for the anti-pattern: "nanoservice".
I could actually imagine someone trying to create UUIDs and not being bothered to implement that functionality correctly in their software.
I hope it'll never happen as relying on a third-party web service has really bad implications, but the world is ready now :)
FWIW, I added support for UUID sets in the API, so now one can ask for thousands UUIDs at once, if one ever needs to :)
As entertaining as this project has been for a few hours, it's time for me to move on.
