Not the OP, but in our product we have very large binaries that are the output of the product itself. Each time a change is made to the program, the output needs to be compared to the existing output first automatically and if the output isn't byte-by-byte identical then manually (visually). So essentially, without large binaries in source control we'd lose testing.
