Except for CSS via Sass I have not used a build process in all these years. And recently I rewrote our CSS to use modern syntax and nesting and variables and etc. - no more Sass! It worked great but then customers started to complain and send messed up screenshots. Turns out a lot of Android phones are using an older browser and a couple of customers were locked into old versions of Chrome by corporate policy. Fortunately this was all nesting rules. So renaming the css file to scss and running it though Sass fixed the issues.
