I think you misunderstand what I mean: I mean that preparing an adventure with all the i's dotted and the t's crossed to a degree implied by the RAW requires a massive amount of time to do, so most people don't.I'm not sure that's true anymore. As the game ages, more and more people become satisfied with (and sometimes overwhelmed by) the amount of rules options they have to choose from.
Look at Dungeon's adventure paths; we can't seriously expect the average DM to put that amount of work into adventure writing...it'd be like a full time job. (Worldbuilding - on the other hand - quite possibly, because people enjoy doing that, and happily sink hundreds of hours into it.) Then again, I think most campaigns are done in a different style that dodges the need to make that time investment (or are simply lower quality). As a result, I think a lot of people are using workarounds.
