Take no risk with legacy.

Before touching working code, weigh it:
frequency of change × risk × cost of refactoring.

If the code never moves, reflection is a cheap way in.

A characterization test (Michael Feathers) freezes today's behavior, bugs included.

Refactoring working code just to make it pretty rarely pays off.

So don't refactor it. Reflect on it.

The mark of great systems engineering: modules that are trivial to replace or delete. When you couple your orchestration logic tightly to a specific cloud vendor's proprietary SDK, you inherit all their pricing shifts and downtime.

Keep your core orchestration vendor-agnostic standard library Python.

Technical Debt: How CTOs Measure, Prioritise and Pay It Down

I love it when the PR has twice that many lines removed compared to the new ones.
