I don’t think it’s a very well adopted extension on any platform. It kind…feels out of place if you think about it. I did see Davx5 supports it, but I’m literally not seeing anything else.

I’m trying to think how it would be implemented in a simpler way than just using date entries and metadata mapping from an implementation standpoint, and I see no functional differences, so I can’t imagine developers really going out of their way to implement it when there’s already an existing and simpler method of essentially doing the same thing.
