Hi Povilas, thanks for the reply.

To be clear, you're saying that implementation in the applications/toolkits ecosystem is the barrier to a better trackpad experience on Linux and that by unifying the feature set of both X and Wayland, this will encourage that implementation among the developers of the applications/toolkits?

If that's correct, that is one angle I had not considered before. It's also somewhat unfortunate that it was not spelled out more clearly in Bill's post, but hindsight is 20-20 of course.
