Since the technical headaches of shooting 3D can slow & limit a production, it's increasingly popular to shoot in 2D and then convert to 3D(ish) in post. So, in the context of indie film, shooting in 3D can really impact your schedule. Also, if you aren't a trained Stereographer, you might shoot hours of flawed or unusable footage, and not know it until later.

probably a PITA to edit too .. i haven't even considered the post production workflow of something like that
From the sound side, it is a royal PITA! You can only really work with a 2D version but constantly have to reference a 3D version and of course, 3D visuals with stereo sound makes even less sense than stereo with HD (or 2k). Most 3D films don't even go with 5.1, preferring one of the so called 3D audio formats, such as Dolby Atmos or at least 7.1.

Sound isn't recorded any differently on set, is it ?
