You are missing the point here ... agreed, most pellet grills have heat deflectors and/or grease trays. Why? Their purpose is twofold -- to create an indirect cooking environment and to channel grease away from the flame. Unless they have a mechanism to move that deflector, they always cook indirect. The SF has a very small heat deflector which allows it to cook somewhat direct and somewhat indirect. Therefore, it never cooks exclusively either way. In trying to build a pit that cooks both ways there had to be compromises. When cooking low and slow (more indirect) there are still some open flames. When grilling direct, some of the flames are blocked. Block the flame too much and higher temps can't be achieved (the pitfall of most pellet grills). Weber chose a small deflector to allowing reaching higher temps, but then sadly they channeled the grease right to the flame. That combination caused a potential issue - grease fires. I don't think Weber was recommending the drip trays for easy cleanup. I believe were suggesting their use to shield the meat from the flame, create a more indirect cooking environemnt and keep the grease away from the flame. If they are recommending trays for that reason, not for just for easy cleanup, they are admitting the design is flawed. So yes, I use foil pans for easy cleanup (just like I foil the deflector on a typical pellet grill). But I am also using another pan to shield the meat from the direct flames to avoid the potential flare up (and if it's a really long cook I might fill it with water). Do I want to have to do so for the life of the cooker? Not really, it get's expensive.
