Thanks @m4rk for your point of view.
Without wanting to make controversy (*), whatever the reason why not even 50 people answer 2 simple questions makes me think about the opportunity to invest “hobby coding” effort in this binding …
To include new features (for example a new WHO), well designed, takes literally several evenings of work and testing, also because OH maintainers rightly require a very high quality code and a lot of precision, something that is definitely not found in other opensource solutions.
Since the official binding in its current state already does everything I need in my personal home environment, adding more features is just a matter of hobby and “fun” in seeing that what you do is useful and interesting for someone.
So if “someone” is only 50 people … well as you can understand, the fun is little 
Maybe people, as you say, come here only when something doesn’t work (the “testing” binding expires soon, we’ll see
) or maybe they have already migrated to other systems: there are in fact other open source solutions, but from what I understand they work badly. Or perhaps many have already migrated to new commercial products / solutions that ultimately no longer require OH.
I do not know the answer. But it is interesting to know.
Bottom line: not even 50 people interested are really much less than I expected.
What do you think?
(*) the reason why there was no update for so long from my side was also because there has been no feedback for so long about inserting the binding in the official OH distribution. Now the situation is very different: all the code is available and the binding is officially integrated in OH2-3. Also: progress maybe is done “behind the curtains” or on github, where actually all the OH contributors are following the progress, maybe not all the users.
