Can you please enable more (or all) opendal backends? Particularly yandex-disk. While Yandex Disk supports webdav its WebDAV support is slower (or flawed) than direct API (and rustic just hangs with it if used*). I bet other backends would be useful for other people too.

Additionally, it would be nice to have some command in rustic that shows supported opendal backends (maybe in --version output).

• BTW, UI of broken wabdav support is confusing as progress indicators just sop printing and nothing happens.
