Good news! Unfortunately I’m not sold on having to have a bridge to access their email using Thinderbird, so I’m not subscribing Proton Unlimited “suite”. Also no working Linux client for Proton Drive (rclone’s is unmaintained and not working).

Negative, full-res photos with EXIF is not possible to access with rclone (due to Photos API limitations).

This is likely via silent updates of Google’s Play Services.
