Addition of new cloud storage provider "Treasure Cloud" that is growing in popularity would be nice.
This cloud storage has a feature where it links other cloud storages such as Gdrive, OneDrive etc, allowing you to access all your drives from one cloud storage.
If rclone's supports this provider, it would make cloud storage a new experience.
Provider Info: Treasure Cloud, Owned by a former Google Employer
based on this from their website, there does not seem to be a API,
without that, rclone cannot support that provider.
