YAML mixes 2 and 4 spaces all the time. Python scripts don't run if you write this kind of crap.

Sure it does. You only need to be consistent within a block. Python's syntax is ridiculous and solves problems that basically don't exist.

All of my java/kotlin/rust/etc. code is trivially well formatted and can be done by my editor. Moving code blocks is trivial. Refactoring is easier when I didn't need to hand -format the code just to make it work.
