This is a shame, because I genuinely find SPARQL over Wikidata one of the most insanely magical things on the internet. It is literally like being able to just query the universe directly and there's almost no end of fun that can be had formulating new questions you can answer and then finding out it's actually possible.

Of course I now feel bad for occasionally hitting it with my frivolous queries, and would be very sad to see it limited.
