I'd expect most cases of stem separation to be handled well by applying specialized software to source music, exporting the stems as audio files, and importing them as individual tracks or samples in the DAW. Are there workflows that benefit from integrating stem separation in a DAW?

It's like a lot of other feature; ease of use. Imagine your DAW only supports import of wav files, you could argue that there are already services / programs that convert * to .wav, so no need to implement that. But if it's build in not only is it one less program to install, it's also convenient.
