Do I keep comments during conversion?

No. JSON has no comment syntax. Round-tripping YAML → JSON → YAML strips comments irreversibly.

What about the Norway problem?

YAML 1.1 parses "no" as false. Quote ambiguous scalars ("no", "yes", "on") or use YAML 1.2 to avoid surprises.

The underlying library follows YAML 1.2, which avoids most of the implicit-type pitfalls in YAML 1.1.
