I think this is a 'right tool for the job' problem. Frequently you don't need an operating system to do basic tasks. I don't see this as a problem at all for simple things to a point. Even something that seems as complex as as reading a sensor and writing data out to a CF card doesn't require an OS if the basic library support is there.
