webDAV servers supporitng atomic writes

When connecting to a WebDAV repository, Kopia provides a --[no-]atomic-writes flag, but I cannot find much information on which WebDAV servers support atomic writes. Is there a list of WebDAV servers for which Kopia can utilise this feature, or a method of verifying that an existing WebDAV server supports atomic writes?

SFTPgo where atomic uploads are configurable.
