Depends on the cloud storage provider, I think. The best chances are with those that support the more standard protocols like S3, webdav, sftp, etc.. A relatively new development is the special remote built into rclone, which should be better maintained than some other third-party special remotes and provides access to all rclone-supported remotes.

Oh, really? rclone is great, but as a standalone thing it's really annoying to use. I didn't realize until now that it was missing a git-annex integration to be great. Thank you! I'll start using it again.
