Yep. Just checked some corpus data and taking soy milk as an example, "soy milk" is used 76.5% of the time by real people not subject to legal shenanigans imposed by the dairy industry, compared to "soymilk" only 23.5% of the time, in the slice of data I looked at. Not the best data (skewed to a certain US locale home to high tech, cable cars, and some large bridges) but pretty overwhelming. And these are people who are being influenced by commercial labels forced by lawsuits to use "soymilk", yet they still separate the words. Usage ftw.
