> Only concern will be dropping support for Ubuntu 16... > I agree that Ubuntu 16 is a bit of an edge case. I think we should proceed forward and we can always provide fixes or a solution for use on Ubuntu 16 (or any other removed OS) if someone raises concerns. It will be important to understand if they need to compile on Ubuntu 16 or just run on Ubuntu 16.

I think it's a good idea to use devtoolset-8 so that we align Centos 7 with Centos 8.
