Is "Proton Mail Export Tool" for macOS vibe-coded?

It feels unlikely to be vibe-coded because this was made like 3 years ago. Even at the beginning of 2025 AI coding was fairly limited. Also this is exactly the quality of product I would expect Proton to make if they don’t care about the functionality. Proton VPN CLI for Linux reached 1.0.0 literally 2 months ago.
