I am still working on your other suggestions, but thought it would be fair to report on my progress.

Regrettably I overstated the performance in my previous post, due to a bug that is now solved. With the solved bug, Pronto is about 50% slower than GDAL directly. I believe this is still good considering the benefits, but not as glamorous as I first thought. I have also applied it on a set of 100000 x 1000 rasters and the results are consistent. 

The related post has been updated (and I still consider it "promising"): https://github.com/ahhz/raster/blob/master/docs/_posts/2018-06-14-Preliminary-benchmark-results-are-promising.md
