Looks like homie and https://w3c.github.io/wot-thing-description/ have a lot in common in terms of describing devices. Wondering if this will have any impact on the future oh homie?

Not yet. W3C WOT is very comprehensive. Homie does only specify entities, and communication structure in a best fit way for MQTT. It is best compared to Mozillas Web Things API (Http+Websockets).

Homie also tries to be json free. WOT heavily relies on a structured format (json as an example, but I think they also allow binary formats like bson etc).

Personally I think a pub/sub transport like MQTT is not the best fit for IoT devices. An IoT device will usually not "subscribe" to anything (that would be a security risk if any network participant could command IoT devices), it will mostly publish. A 1:1 device<-->controller connection often makes more sense.

But as long as MQTT is used in the DIY IoT sphere, Homie will be there.
