In 1.7.10 there were certain blocks that were either in the "Technical" category or their own, specifically the more-realistic looking concrete (compared to the less realistic Vanilla concrete) and the Technical Block's Worn Concrete that seem to be missing in the latest 1.10.2 version. I'm asking if its possible for them to be re-added.

There are a lot of missing variations, that I miss. There was a particularly nice looking cobble variation that made a very convincing rough/realistically weathered wall that I used extensively in my 1.7 builds which is missing from 1.10.

Is there an ETA on the re-introduction of iron bar chiselling?
