The reality is that "either way can work and either way can fall".

For at the bottom of this thing lies the actual song itself. If it can "stand alone" it will likely still get attention. There have been rather recent examples of just that happening.

On the other hand, you should find out what your target wants you to submit. If you are submitting to a house that routinely solicits for fully fleshed out demos, it would be of benefit for you to pursue the same path.

But again, whether your demo is a simple voice-and-guitar or a fullblown production number, it is the songwriting itself that sells the work. Or not.
