No, you are completely right, and I think that's the direction the original question/comment leads to: there is already a known preference (in the browser settings, OS settings, account history) to have a better prediction of what the user wants - and the possibility of adding settings to override/change that if needed! Instead, every site/service/app is just trying to guess, and often enough guesses wrongly.
