But they already implemented it with their web client and iOS/Android clients. And with GopenPGP they have a golang library for the encryption. If they opened up (aka documented) their API it could be possible for programs like rclone to implement Proton Drive. If they also documented how they expect the GPG encryption and GPG signatures to be done then everything would be good to go for 3rd party devs.
