I noticed someone implemented conditional reads for WebDAV (https://github.com/apache/opendal/pull/7637) and was wondering about conditional writes. There seemed to be several tracking issues for conditional writes but they're all closed (https://github.com/apache/opendal/issues/4074, https://github.com/apache/opendal/issues/5218). Is there an existing tracking issue I'm missing or should I create one? Another related question. I wasn't able to find a documentation page with which specific native capabilities are supported by each service (there is of course the capabilities list on the service struct documentation pages, but it doesn't mention all capabilities). I can make it if it doesn't exist.
