You have a point there; I didn't because everything I've seen is that people like the results of Bazel, but they hate writing rules, so Bazel rules seemed like something to not emulate. But point taken. And thank you for the explanation. It seems providers allow for multiple outputs on a target. My build system allows that, but bundling such outputs together is a good idea that I need to add.
