I don't think the OP is arguing for a system-wide default prompt, but rather the ability to add his own default prompt. I think that would be quite useful. Something like "add 'think step by step, be concise' to all my prompts, unless I include '/noboilerplate' in the prompt". Same for other systems. I recently generated dozens of images with Midjourney, which I wanted to all be in the same style. It sure would have been nice to tell it "add [artistic movement] illustration in the style of [artist]" to every prompt", without typing it in manually every time.
