I've forgotten more Sql than most people ever learn. Time is also valuable and I make trade-offs. Should I spend hours (eg. $$$) to optimize or run a non-optimized query in the background for a different cost? Well, I didn't think the time/benefit/cost equation favored tuning, if I had known that I'd have spent time on tuning. If you offer something for "free" and then change the cost, and don't have any alerting mechanisms to inefficient queries, it's impossible to evaluate trade offs.
