I think this is a great lesson for the community. It would have been easy to write off the GeoPackage and just let there be this schism between OGC formats and Esri formats, but both sides of that discussion realized that the real scourge (editor’s note: my iPad autocompleted scourge as scumbag, I think that works as well here) of data formats is the Shapefile. The sooner this DBF infused madness ends, the sooner data can start being whole again.
Someone asked me if I was happy being proved wrong. I don’t look at it that way. I was never saying the GeoPackage wasn’t a great idea, I mean read all my blog posts from late 2012/early 2013. Without Esri support, the format was really going nowhere. But Esri has smartly embraced the GeoPackage over the last few years and now with ArcGIS Pro 2.6, we can natively use it with out GIS software, no matter what platform you are on.
