Questions

Are comments kept?

No — the YAML is parsed and written back out, so comments are dropped. Keep a copy if your comments matter.

Why are some strings quoted?

Values that YAML would otherwise read as numbers, booleans or dates are quoted so their meaning doesn’t change.

Can it sort keys?

Yes, alphabetically at every level — handy for diffs and config reviews.
