I have reached out to X-plane by e-mail and I received a response with regards to Vive support.
In the response he said that HTC Vive support is definitely coming to X-Plane 11 sometine 2017. No specific date given as of yet but rest assured when that happens, there will be no need to get a 3rd Party addon that does that for you.
