Your walls are already covered in lacto/pedio/brett/klock/etero/etc, and you dont worry about this because you sanitize your equipment before using it
The bugs in a sour blend are no different than anything already living on all the surfaces in your house, they also will not come out of the airlock
I ferment my sours directly next to my "clean" beers, and even use the same carboy for either type.
I think there is too much fear of wild bacteria when someone considers brewing a lambic/etc. I have a feeling this comes from the big breweries concerns about contamination, but they are worried about transfer lines etc, we dont have to worry about that, and its very easy to disassemble all of our equipment to clean - I even use the same racking cane and tubing
