Default Homodyne/Direct Conversion

Having read Al's ( Skywave) general question about short superhet definition it made me think about Direct conversion receivers. Without interfering with his thread I set this thread off to answer the simple question of why direct conversion is not widely used as opposed to a superhet design.

Ideally the Homodyne is simpler and uses less stages and components, more efficient detection and does not suffer the effects of image frequencies etc.

Why has it not been more widely used in not just Domestic but also in Commercial radio.
