It's often the source of a good portion of the queries and load in web applications. Multiple joins and more than one row... I have several time seen stats changes or bad to-be-sorted columns cause large amounts of memory to be used. Anyway, I've stated my opinion that I do not think it's a good idea to raise that particular default (while agreeing with all the others) and I know I am in the minority, so I don't think we need to argue this out...
