Fair enough, I should have thought about the Qt-based stuff :),
especially since I have been following it quite closely.

My question just boils down to: is it worth giving this win to end users
while removing other things they already have? Should a '0.X' release
ever temporarily remove features that will come back later? As an
outsider from a project, I expect the feature set always to be
increasing, or to be simply features to be dropped.

I agree with the progress. I can see the gain. It's great, but it seems
to be more of a developper point of view that an end user point of view.

Absolutely, I have been witnessing this and I can tangibly feel this
improvement. There has clearly been a shift in the project's dynamics
that is awesome. 

Anyhow, it won't impact me much, because at work we are stuck with really
old stuff (.8, I believe), and I myself already use the latest code from
git updated every once in a while. I am just wondering if, from the point
of view of the end user, it is not worth waiting another 6 months to have
things stabilize a bit more. Release an 'alpha', or 'technology preview'
might be a better message to give.

Now I am just going to shut up, and watch the fantastic progress that is
being made.
