With an aftermarket turbo, it's sometimes the only way to mount a filter. I had to relocated a battery and fusebox just to fit a turbo on my old car. And I ran just screen until I found a filter that worked, had to get one of those HKS mushroom style ones. Most aftermarket kits are built to just fit, they're not necessarily designed with other factors in mind.
Nothing wrong with venting to the atmosphere. Anyone with a BOV is basically doing that. My AA BOV vents to atmosphere. Not such a huge deal since we run a MAP sensor. If you have a MAF sensor, you'd have to account for that air somehow. But your diverter valves would not be diverter valves because technically, they're not diverting if you vent them to atmosphere. No need for filters either. The valves are closed until they vent, so nothing gets in. Notice that BOV's don't run filters since air only goes one way. No bugs or dirt can get in since they're closed most of the time.
