🤔 What's changed?

Use a message based usage formatter. Reworks the usage formatter to be useful too. Does change the json structure significantly.

⚡️ What's your motivation?

Contributes towards #3001.

🏷️ What kind of change is this?

• 🏦 Refactoring/debt/DX (improvement to code design, tooling, etc. without changing behaviour)
• ⚡ New feature (non-breaking change which adds new behaviour)
• 💥 Breaking change (incompatible changes to the API)

♻️ Anything particular you want feedback on?

In its previous state the formater doesn't seem useful. So I'm okay with making this a breaking change. Should this give you particular problems, please create a new issue.
