I don't want limits on the kinds of queries I can run when those limits are artificial ones imposed to work around limitations of a too-simple billing system instead of being inherent in the domain. I'm willing to pay extra for the occasional huge query, but I wouldn't feel comfortable knowing I couldn't make it at all.

How much overlap is there in the “serverless database that starts fast” group and the “might have a query that runs for 60 sec” group? If you’re running queries that are that complex, wouldn’t you be better served with a different database service?

If I used two services, I'd have to move data from one service to another.

That said, a production OLTP workload database would also have query timeout imposed, otherwise those fine folks in the crappy query writing department will surely bring it down.
