If you have known the structure of the Wayland protocol before making the comment, you'd know that "official support" is a red herring.
The only official thing provided by the Wayland project (other than the protocols themselves described in XML) is the wayland-server and wayland-client library pair, which is more or less just a serializer and deserializer of the protocol.
There is also Weston, but we don't talk about it.
Waypipe is about as official as Kwin, Mutter or wlroots, and yet we don't disregard those projects as being irrelevant due to their unofficial status.
