IIRC, this was actually a thing in Rails 2 and it got taken out. I agree with you about the convention over configuration idea, but when you only need the one line of code to get it back, and it relieves a maintenance burden and makes things faster, I'd have to side with it not being in core.
That being said, this is one of those things that would be great for a gem to provide automatically (basically on initialize search through for every boolean column and set up scopes). Sounds like a good project if you've got time to take it on.
