A major element of the 5.6 changes (documented in an article not yet written, but should be by early next week) is to protect Jimmy the junior dev from himself - chances are that an inexperienced dev, given the choice between a one-liner and several lines with a bunch of scary-looking options, is going to pick the former. I'm not advocating it, just stating it.
The next article will cover the changes in 5.6 and why you don't need to set those ctx opts any more (and a few more you might want to set instead)
